A Fourth Revolution in the Use of Resources

October 1, 2024

When is a resource especially useful? The answer often varies based on the technological advancement of the society in question. Human capital is especially susceptible to this variable, as it is only as useful as its carrier’s tools are. In this Fourth Industrial Revolution, the knowledge worker’s debut is the consequent shift of human capital owing to information technologies such as the computer and artificial intelligence. Just how monumental this shift may be is to be analyzed.


Historically speaking, few resources aside from hard currency like bullion and necessities like water have maintained a constant degree of usefulness. Clearly, an abundance of fossil fuels offers a different meaning to a hunter-gatherer tribe and an industrialized nation just as a plentiful supply of spices means different things to a medieval European kingdom and any country today. More often than not, though, these differences in meaning can be attributed to differences in technology. A hunter-gatherer society has no means and no purpose to exploit fossil fuel technology, while any industrial nation will demand (at least for now) a constant supply of non-organic energy due to lighting systems that require the energy from fuels. Even the disparity in significance of spices can be attributed to technology, however indirectly. The medieval European kingdom was at the mercy of the Italian merchants, Ottoman sultans, and Indian planters to attain expensive spices, especially without any technologies in the fields of preservatives, cultivation, or transport. By contrast, today’s globalized trading network, mixed with extensive advancements in preservatives and wider spice cultivation have reduced salt and pepper from the most expensive commodity on a continent to a kitchen counter constant. Typically, changes in the usefulness of resources go in tandem with shifts in the technologies that put them to use. The introduction of steam power in the Industrial Revolution, for example, necessitated the use of coal and other fossil fuels. Great Britain’s vast underground coal reserves, thus, suddenly became a valuable asset to the country in propelling it to industrial powerhouse. These shifts can also go the other direction. With the rise of oil- and diesel-powered combustion machines in the 20th century, those same coal reserves declined in significance, reducing Britain’s industrial advantage.


Human capital is not exempt from these shifts in usefulness. Engineers became of great use whenever the technologies to develop siege weapons (as well as the capital and organization to build them) became available to states; Roman and Chinese armies of antiquity employed great numbers of siege engineers. Similarly, architects were commissioned whenever the means of building elaborate structures became available; the Renaissance abounds with examples of this. 


Thus, the Fourth Industrial Revolution (or more aptly the Digital Revolution) will enact unique shifts in the usefulness of workers and resources alike, thanks to the nature of the technology involved: the computer. Though Drucker passed away in 2005, he foresaw the rise of artificial intelligence within his predictions about the computer in “What the Computer Will be Telling You” (date unknown), calling out its potential to analyze data akin to what artificial intelligence does nowadays.


This brings meaningful shifts for all levels of human labor. The combination of computing with robotic technology and affordability has made it possible for unskilled labor to be replaced en masse, reducing the use for unskilled labor. Even lower-level white collar jobs like clerks and accountants face stiff competition given their work is repetitive at a digital level and liable to be replaced by artificial intelligence. The one field of employment that is expanded as a result of these technologies is the knowledge worker. Partially born from the growth of computing technology, partially an existing beneficiary of said technology, the knowledge worker performs their work on the premise that the grunt work of crunching numbers and calculating growth metrics can be easily done by the tools at their disposal.


In an economy where physical production is a linear metric of economic performance, the knowledge worker has limited use. In such an economy that furthermore relies on a chain of human calculators and analog communication, the knowledge worker is extremely limited in capability and is thus not a significant factor in economic output. Hence why the knowledge worker has only risen to prominence within postindustrial economies.

Thus, the American economy is especially susceptible to shifts in usefulness as one of the most postindustrial economies on the planet. This has significant consequences for its future economic prospects. For one, it was able to reach its status as a global powerhouse due to the growth of its giant manufacturing base, which took place between the Civil War and World War II. Its further investment in STEM education, priority on innovation, and corporate dominance during the Cold War allowed it to keep its top position throughout the 20th century. However, the Fourth Industrial Revolution has introduced some subtle changes to the economic calculus that necessitate reform of the current system. 


For one, even though the American economy is already heavily service-based, the automation of tasks at the lower level combined with the augmentation of capabilities in the office means the labor shift is geared towards prioritizing higher educated workers as primary human factors of economic output. Given much of the service sector is not necessarily aligned with knowledge work, the usefulness of the service sector in general is skewed upwards in terms of human capital. 


For another, the productivity of the knowledge worker rests with both production and mentality. Drucker stressed the autonomy of the knowledge worker as one of their defining characteristics, made possible by the powers of computing and AI. Because the complex calculations are automated by these technologies, that leaves the decision-making up to the human. Of course, the knowledge worker must still be trained in the technical skills required to use the tools at their disposal. However, the decision-making facilities of the knowledge worker, including foresight and rationality, matter greatly if they are to efficiently perform their job. 


The future competitiveness of the American economy, and by extension many other economies, is dependent upon this. In its manufacturing heyday, the United States was the world’s superpower due to its towering advantage in scale over its European counterparts and the absolute lack of industrialization elsewhere in the world. During the Cold War, the United States once again strode the world economically due to sheer scale, concentration of capital, and worker efficiency. Now, however, economic disparities in the world have narrowed. After rapid industrial development in the twentieth century, East Asia has caught up to America in terms of economic development and has even surpassed it in certain fields like semiconductors. Developing nations, most notably the BRICS countries, have become manufacturing leaders. China in particular has bridged being both the “world’s factory” and a center of highly educated talent. What this all means is that the United States cannot rely on simple scale and the virtue of being the earliest as it did in the past. The combination of knowledge workers requiring extensive high-quality rearing and the dilapidated nature of American institutions like education and infrastructure puts the country at risk of losing its economic edge in the world. 

However, the American economy is not consequently destined to decay. Its national culture of pursuing individual advancement and success is well-fitted for the world of the knowledge worker. It already possesses a well-educated population that has been used to living in a developed economy for a century. It holds the largest concentration of financial capital in the world. While this by no means encourages complacency, it simply means the country must pursue a different utilization of its resources in order to keep its current economic position in the world. It cannot compete in human numbers, for India and China boast populations far larger and countries like Indonesia and Nigeria are quickly catching up. It cannot compete in manufacturing, as Brazil and China are now the biggest producers of the commodities that America dominated over a century ago. Even in higher-tech industries like semiconductor chips, countries like South Korea and Taiwan have demonstrated that small populations can easily and quickly trounce less-prepared competitors many times their sizes, as the United States has learned of late. So ultimately, the United States ought to perceive that through the synergy of its relative strengths in all the aforementioned fields with investment into cultivating a robust knowledge worker base, it will be best positioned to retain its premier status as a global economic leader.


In conclusion, the American economy will have difficulties adjusting to this new reality in spite of its current advantages in education and economic maturity. What matters most - not only for the United States but for the other economies of the world - is that with the Fourth Industrial Revolution, the usefulness of labor will play a defining role in each country’s economic standings. Those that grasp this concept will prosper, while those that neglect it will fall behind. The use of the knowledge worker, and subsequently the highest level of human capital, will become top priority.

Peter Drucker’s memoir, Adventures of a Bystander, is a self-portrait of a most unusual kind. It reveals its subject not through direct autobiography, but through a series of incisive portraits of the people he encountered throughout a tumultuous life. Drucker positions himself as a "bystander," but this is no passive observer. Instead, he is an intellectual portraitist whose careful study of others becomes the very method by which he comes to understand himself and the fractured world he inhabited.

This essay was inspired by an article recently published by Karen Linkletter and Pooya Tabesh (2025). They were in search of the meaning of “decision” in the works of Peter Drucker. To this end, they used Python to identify and locate all the times the word, “decision”, came up in Peter Drucker’s oeuvre . They then characterized the contexts (“themes”) in which the word came up. The result was a nuanced but very clear characterization of the evolution of his thinking on the topic. Here, we will focus on a key theme for Drucker: the case where your decisions involve other people’s decisions and actions . For present purposes, we can start with their statement: One of Drucker’s valuable contributions to the literature on decision-making is his adamance that implementation be built into the decision-making process.” (Linkletter and Tabesh 2025 8) To be clear, “…it is not a surprise that his integration of implementation of and commitment to decisions is part of his process of decision-making. He argues that a decision “has not been made until it has been realized in action.” (2025 8) The question, therefore, is how to make this happen, how to turn an organization from an aggregate of individuals whose decisions may or may not be aligned, into an agent—an entity that makes decisions, implements them, and then ascertains that what was done was, in fact, what was decided, as we try to do when making purely individual decisions. Let’s look at the matter more closely… A few years ago, I read a story about a road crew that was painting a double-yellow line on a highway. In their path was a dead raccoon that had been hit by a car or truck. It was lying right in the middle of the road. The crew didn’t stop. Someone later took a picture of the dead raccoon with a double-yellow line freshly painted right over it. The picture is below. It went viral on the Internet.

When Paul Polman became CEO of Unilever in 2009, he did not inherit a troubled company. He stepped into a large global enterprise with familiar consumer brands that sat on shelves in cities from Amsterdam to Manila. Even with that scale and reach, the business rested on foundations that were beginning to crack. Public faith in multinational firms was fading, climate change was moving from a distant worry to a financial reality, and investors were increasingly locked into the rhythm of quarterly results that encouraged short term decisions and discouraged real strategy.

Peter Drucker suggested that readers view his first three books as a unified body of work: The End of Economic Man(1939), The Future of Industrial Man (1942), and Concept of the Corporation (1946). These works share a common theme: politics. Drucker did not think about politics like scholars who strictly follow modern social science norms. Instead, he viewed politics as part of social ecology and understood political events through the dynamic changes in social ecology. Despite having "corporation" in its title and using General Motors as a case study, Concept of the Corporation is indeed a book about politics. In this work, Drucker attempts to address the main issues that industrial society must resolve: the legitimacy of managerial authority, the status and function of managers and workers, and the power structure of society and organizations. In Drucker's own words, this is a book exploring the specific principles of industrial society. Corresponding to these specific social principles, Drucker had earlier attempted to develop a general social theory, which was the aim of The End of Economic Man and The Future of Industrial Man. The subtitle of The End of Economic Man is "The Origins of Totalitarianism." The book focuses on how society disintegrates in industrial societies and how totalitarianism rises. For Drucker, the real challenge of this topic isn't explaining how Hitler and Mussolini came to power, nor the actions of Germany and Italy in government, military, and economic spheres. Rather, it's understanding why some Europeans accepted clearly absurd totalitarian ideologies, and why others seemed potentially receptive to them. Drucker's writing style is argumentative. He clearly knew that to effectively advance his arguments, he needed to engage with popular theories of his time. Back then, there were two main explanatory approaches to Nazism and Fascism, which Drucker termed "illusions." Some viewed totalitarianism as ordinary political turmoil similar to previous historical revolutions. In their view, totalitarianism was characterized merely by cruelty, disruption of order, propaganda, and manipulation. Others considered totalitarianism a phenomenon unique to Germany and Italy, related to their specific national characters. Drucker thoroughly refuted explanations based on "national character." He believed that any historical approach appealing to "national character" was pseudo-history. Such theories always emphasize that certain events were inevitable in certain places. But all claims of "inevitability" negate human free will and thus deny politics: without human choice, there is no politics. If the rise of totalitarianism were inevitable, there would be no need or possibility to oppose it. Viewing totalitarianism as an ordinary revolution is equally dangerous. This thinking merely emphasizes how bad Nazis and Fascists were. But the real issue is that Europeans were not merely submitting out of fear—they were actually attracted to totalitarianism. And those attracted weren't just the ignorant masses but also well-educated intellectual elites, especially the younger generation. The world cannot defeat totalitarianism through contempt alone, especially if that contempt stems from ignorance. Understanding the enemy is a prerequisite to defeating it. Drucker identified three main characteristics of Nazism and Fascism (totalitarianism is a social type, with Nazism and Fascism being its representatives in industrialized Europe): 1. The complete rejection of freedom and equality, which are the core beliefs of European civilization, without offering any positive alternative beliefs. 2. The complete rejection of the promise of legitimate power. Power must have legitimacy—this is a long-standing tradition in European politics. For power to have legitimacy means that it makes a commitment to the fundamental beliefs of civilization. Totalitarianism denied all European beliefs, thereby liberating power from the burden of responsibility. 3. The discovery and exploitation of mass psychology: in times of absolute despair, the more absurd something is, the more people are willing to believe it. The End of Economic Man develops a diagnosis of totalitarianism around these three characteristics. Drucker offers a deeper insight: totalitarianism is actually a solution to many chronic problems in industrial society. At a time when European industrial society was on the verge of collapse, totalitarians at least identified the problems and offered some solutions. This is why they possessed such magical appeal. Why did totalitarianism completely reject the basic beliefs of European civilization? Drucker's answer: neither traditional capitalism nor Marxist socialism could fulfill their promises of freedom and equality. "Economic Man" in Drucker's book has a different meaning than in Adam Smith's work. "Economic Man" refers to people living in capitalist or socialist societies who believe that through economic progress, a free and equal world would "automatically" emerge. The reality was that capitalism's economic freedom exacerbated social inequality, while socialism not only failed to eliminate inequality but created an even more rigid privileged class. Since neither capitalism nor socialism could "automatically" realize freedom and equality, Europeans lost faith in both systems. Simultaneously, they lost faith in freedom and equality themselves. Throughout European history, people sought freedom and equality in different social domains. In the 19th century, people projected their pursuit of freedom and equality onto the economic sphere. The industrial realities of the 20th century, along with the Great Depression and war, shattered these hopes. People didn't know where else to look for freedom and equality. The emerging totalitarianism offered a subversive answer: freedom and equality aren't worth pursuing; race and the leader are the true beliefs. Why did totalitarianism reject the promise of power legitimacy? One reason was that political power abandoned its responsibility to European core beliefs. Another reason came from the new realities of industrial society. Drucker held a lifelong view: the key distinction between industrial society and 19th-century commercial society was the separation of ownership and management. The role of capitalists was no longer important. Those who truly dominated the social industrial sphere were corporate managers and executives. These people effectively held decisive power but had not gained political and social status matching their power. When a class's power and political status don't match, it doesn't know how to properly use its power. Drucker believed this was a problem all industrial societies must solve. Totalitarianism keenly perceived this issue. The Nazis maintained property rights for business owners but brought the management of factories and companies under government control. This way, social power and political power became unified. This unified power was no longer restricted or regulated—it became the rule itself. Why could totalitarianism make the masses believe absurd things? Because Europeans had nothing left to believe in. Each individual can only understand society and their own life when they have status and function. Those thrown out of normal life by the Great Depression and war lost their status and function. For them, society was a desperate dark jungle. Even those who temporarily kept their jobs didn't know the meaning of their current life. The Nazi system could provide a sense of meaning in this vacuum of meaning—though false, it was timely. Using the wartime economic system, the Nazis created stable employment in a short time. In the Nazi industrial system, both business owners and workers were exploited. But outside the industrial production system, Nazis created various revolutionary organizations and movements. In those organizations and movements, poor workers became leaders, while business owners and professors became servants. In the hysterical revolutionary fervor, people regained status and function. Economic interests were no longer important, freedom and equality were no longer important; being involved in the revolution (status) and dying for it (function) became life's meaning. The Nazis replaced the calm and shrewd "Economic Man" with the hysterical "Heroic Man." Though absurd, this new concept of humanity had appeal. What people needed was not rationality but a sense of meaning that could temporarily fill the void. Those theorists who despised totalitarianism only emphasized its evil. Drucker, however, emphasized its appeal. He viewed totalitarianism as one solution to the crisis of industrial society. From 19th-century commercial society to 20th-century industrial society, the reality of society changed dramatically. 19th-century ideas, institutions, and habits could not solve 20th-century problems. Capitalism could not fulfill its promises about freedom and equality, and neither could Marxism. It was at this point that totalitarianism emerged. Nazism and Fascism attempted to build a new society in a way completely different from European civilization. Drucker said the real danger was not that they couldn't succeed, but that they almost did. They addressed the relationship between political power and social power, proposed alternative beliefs to freedom and equality (though only negative ones), and on this basis provided social members with new status and function. The war against totalitarianism cannot be waged merely through contempt. Defeating totalitarianism is not just a battlefield matter. Those who hate totalitarianism and love freedom must find better solutions than totalitarianism to build a normally functioning and free industrial society. Totalitarianism gave wrong and evil answers. But they at least asked the right questions. Industrial society must address several issues: the legitimacy of power (government power and social power), individual status and function, and society's basic beliefs. These issues became the fundamental threads in Drucker's exploration of industrial society reconstruction in The Future of Industrial Man. The Future of Industrial Man: From Totalitarian Diagnosis to General Social Theory Both The End of Economic Man and The Future of Industrial Man feature the prose style of 19th-century historians. Even today, readers can appreciate the author's profound historical knowledge and wise historical commentary. For today's readers, the real challenge of these two books lies in Drucker's theoretical interests. He doesn't simply narrate history but organizes and explains historical facts using his unique beliefs and methods. In The End of Economic Man, Drucker developed his diagnosis of totalitarianism around three issues: power legitimacy, individual status-function, and society's basic beliefs. In The Future of Industrial Man, he also constructs a general social theory around these three issues. In "What Is A Functioning Society," Drucker explains three sets of tensions that exist in social ecology:

When Marc Benioff founded Salesforce in 1999, Silicon Valley had a pretty straightforward playbook which was technological disruption at any cost. Profit, scale, and market capture dominated corporate ambition. Benioff, who worked under Steve Jobs at Apple and explored Buddhist philosophy, was not satisfied with that approach. He envisioned a company that would not only revolutionize enterprise software through the cloud but also redefine the social purpose of business itself. His leadership at Salesforce reflects Peter Drucker's concept of Management as a Liberal Art (MLA). This idea holds that management is not just about efficiency or growth, but about making work human, creating meaning, and building institutions that serve society (Drucker, 1989).

Previously, I shared de Tocqueville’s concept of equality of condition and how it is manifesting in today’s perception that democracy has failed to deliver on its promise of economic and social equality for all. Promises of economic equality are impossible to fulfill; but democratic societies can and should offer all of their members dignity and a sense of purpose. In this final installment, I’ll share de Tocqueville’s prescriptions for shoring up the institutions of a democratic society – as well as some of his warnings about challenges that democracies face.

Over the past two decades, there has been a discernible shift in the professional workforce. Increasingly, individuals have chosen to leave traditional corporate environments in favor of smaller ventures, entrepreneurial efforts, and purpose-driven careers. This migration has been fueled by a desire for greater autonomy, meaningful impact, and freedom from the rigidity of hierarchical organizational structures. As the world continues to undergo sweeping changes—economic, technological, and social—professionals are finding themselves at a crossroads. The COVID-19 pandemic only accelerated this reckoning, forcing people across industries to reevaluate their relationship with work, identity, and independence.

In Part I of this series, I gave a brief overview of Alexis de Tocqueville’s background and project of evaluating American Democracy in the early 19 th century. In this new installment, I’d like to share de Tocqueville’s observations about the nature of equality in America and how what he saw might help us understand some of the challenges democracies face today.
