"Once a complex society enters the stage of declining marginal returns [marginal economic costs higher than marginal economic benefits], collapse becomes a mathematical likelihood, requiring little more than sufficient passage of time to make probable an insurmountable calamity." Joseph A. Tainter (1949- ), American anthropologist and historian, (in his book, The Collapse of Complex Societies 1988).
"All who attain great power and riches, make use of either force or fraud; and what they have acquired either by deceit or violence, in order to conceal the disgraceful methods of attainment, they endeavor to sanctify with the false title of honest gains." Niccolò Machiavelli (1469-1527), Italian political philosopher and author of The Prince, 1513, (in Florentine Histories, 1526, book III, ch. 13).
"There is no question tariffs can be an act of war to some degree and could cause inflation... Trade should not be a weapon." Warren Buffet (1930- ), renowned American investor, comments made on March 3, 2025, in a TV interview with CBS News and at the Berkshire Hathaway's annual meeting on May 3, 2025.
Since the beginnings of the first Industrial Revolution in the mid-18th century (initially in Britain in 1750-1760), and later in France and in other countries), democratic societies and industrial economies have tended to become increasingly complex, moving from subsistence agricultural and artisanal systems to stages of urbanization and increasingly sophisticated technological advances.
In the 19th century, advances in means of transportation with the advent of steam-powered ships and trains stimulated industrial specialization and international trade. In the early 20th century, it was the availability of petroleum-based liquid energy that propelled the automobile and aircraft industries. Subsequently, energy generated by hydroelectricity served as a propellant not only for widespread electrification but also enabled the emergence of new industries.
Similarly, important economic, technological and institutional progress was a powerful factor of the post WWII period, especially from 1945 to the early 1970's, which saw a boom of general economic prosperity and of social progress.
Later on, the advent of the Internet and satellites also played a significant role in communications and the economic and financial globalization that followed. And now, in the 21st century, the revolution in Artificial Intelligence and automated robotization could upend the way businesses and industries operate.
However, studies by various writers on civilizations and their growing economic and political complexity have identified a number of causes and factors that could lead to a slowdown, if not a decline, in the economic order and efficiency of the previous century. There is a fear that neglected or unresolved problems, intellectual confusion and social disintegration could lead to widespread chaos and to a period of political and social disruption and economic stagnation.
More specifically, historians and social scientists such as Arnold J. Toynbee (The Study of History, 1962), Joseph A. Tainter (The Collapse of Complex Societies, 1988), Jared Diamond (Collapse: How Societies Choose to Fail or Succeed, 2005), and Samuel P. Huntington (The Clash of Civilizations, 1992) have highlighted the risks and vulnerabilities that can arise when economic and political systems become increasingly complex and bureaucratized, and increasingly fall victim to unforeseen domestic or external demand and supply shocks.
In which case, the well-being and economic prosperity of an entire population in some industrial societies could be at risk. The collapse of the Soviet Union under the weight of the contradictions of its economic and bureaucratic system, in 1991, serves as a reminder that such collapses or declines did occur many times throughout history.
A first question therefore arises: even if we limit our thinking to the most important economic factors, could the same causes that brought about the collapse of ancient complex economies and societies in the past possibly apply to some industrial societies of today? Secondly, as a caveat, it is also useful to remember that once a process of decadence is set in motion, it may take a few decades before it is fully realized.
I) Public sector debt levels and the debt trap problem
Some spendthrift Western governments have tolerated persistent fiscal deficits over the last decade, especially since the 2008-2009 Great Recession. In so doing, they run the risk of letting their public debt, as compared to the underlying economy, reach unsustainable and counterproductive levels.
Such fiscal laxity raises intergenerational issues. Indeed, public debts are a form of deferred taxation. This could mean higher taxes in the future.
In the short-run, this could also lead an economy into a debt trap, that is, a situation where a vicious cycle of large fiscal deficits and higher public debt levels as a percentage of domestic production, coupled with rising borrowing costs, does not stimulate but rather slows down the economy.
Indeed, a fiscal crisis looms on the horizon when public debt reaches levels that are too high relative to an economy's gross domestic product (GDP).
Normally, when public debt is not excessive, i.e. when the public debt-to-GDP ratio is relatively low, any additional public spending financed by borrowing propels economic growth upwards. The public spending multiplier, or Keynesian multiplier, is then greater than unity, meaning that one dollar of additional public spending produces an increase of more than one dollar in overall economic spending (public and private) and higher economic growth.
However, empirical studies by economists Reinhart & Rogoff (2010) show that when the public debt-to-GDP ratio for an economy reaches 90%, a debt trap is likely to appear, because the multiplier of public spending may then not exceed 1.0, which means that one additional dollar government spending produces less than one dollar of economic growth.
The main reason is that unproductive debt service (interest and repayment) comes to occupy a growing share of the public budget. This can lead to an increase in interest rates and taxes and force a contraction in public spending. The economy may then find itself in a situation of economic stagnation and inflation, which is the definition of stagflation.
The worst thing to do in such circumstances is to finance current public expenditures with more debts, rather than through taxes.
The average public debt level of the 38 OECD member countries, measured as the public debt-to-GDP ratio, after exceeding 120% in 2020, was still above 100% in 2024, according to official data. Countries with a public debt-to-GDP ration above 100% are Japan, Greece, Italy, the United States, France, Portugal, Spain, Belgium, the United Kingdom, and Canada.
Over-indebted governments will not be in a good fiscal position to cope with a major economic crisis in the future.
II- Other leading indicators of economic trouble ahead
Economic leading indicators can provide early warnings of changes in the direction of an economy in the coming months or years. Examples can be sudden changes in monthly jobless claims, a rise in the ratio of new part-time jobs to new full-time jobs, a decline in consumer confidence, a decline in new orders for manufactured goods or a general increase in tariff barriers, etc.
Such indicators could signal when a potential economic downturn or a recession is about to unfold.
The current economic and financial environment is special because for months, many leading indicators have been pointing to an economic downturn, but partly because of unusually high public deficits, most economies have shown some resilience and a recession has been postponed.
In the past, when this has occurred, such as in the late 1970's, the subsequent economic recession was more severe than usual. In fact, there were two important worldwide economic recessions in 1980 and 1981-1982.
Therefore, the lesson of history seems to be that when an important rise in public debt postpones artificially the onset of a recession, the next economic downturn risks being even more severe.
III- The Trump administration's disruptive tariffs and on-coming job losses
In 1930, American tariffs in the republican sponsored Smoot-Hawley Act turned an economic recession into an economic depression for both the United States and for the world economy.
Politically, it also brought down the U.S. Republican Party. The Democrat Party took over power in 1933, with the Franklin D. Roosevelt administration and its New Deal. Democrats remained in power for twenty years, until in 1953, when the Republican Party under Dwight D. Eisenhower regained power.
Some ninety years later, the Republican Trump administration's unilateral tariffs on imports risk upending international trade again for years to come.
This could possibly lead to a 'Trump Slump' and the loss of millions of jobs, not only in the United States but also around the world, if short-run partisan political considerations were to prevail over long-term economic logic.
IV- The climate crisis, the energy crisis and international migrations of populations
In the past, a major cause of productivity gains and economic growth has been access to cheap and reliable sources of energy. Whether coal, mainly for steam engines in ships and trains, or liquid energy derived from oil and gas for automobiles and airplanes, or electricity from hydroelectric or nuclear power, these energies have increased labor productivity tenfold and raised living standards.
Nowadays, climate warming that is expected until the end of the century to be the cause of more floods and droughts, threatens to disrupt the economies of several countries, as well as international agricultural supply chains.
For environmental reasons, governments are seeking to discourage the use of polluting fossil fuels and replace them with renewable energies such as solar and wind power, which are less reliable and often more expensive. Higher energy costs could act as a brake on future economic growth.
For underdeveloped economies with high population growth, population migration to economies with high living standards is likely to intensify. Such migration is already causing serious problems of social and cultural integration, particularly in Europe and North America.
V- Incompetence, improvisation and confusion in some governments
There is a daily demonstration that there is currently in the United States a dysfunctional, chaotic and erratic federal government that is dangerously unhinged, especially as it is bent on launching a risky international trade war, which irresponsibly threatens to severely contract world trade and upend numerous national economies.
In Europe, especially within the Euro zone, some countries seem to have de facto moved away from the statutory limits imposed on their public budget deficits and indebtedness.
All this could have something to do with the increased influence of big money into the working of the political system in some countries. The often lack of expertise of many of the world's most powerful leaders in situations of conflicts of interests has become a great challenge to the principles of good public governance, as this is reflected in their policies and decisions.
Conclusion
Modern economies and societies have become ever more complex systems, especially in the Western world. Multiple factors may contribute to their decline, involving economic, political, fiscal, environmental, demographic, speculative, social and cultural crises. There has been an expansion of public or semi-public bureaucracies and monopolies, which can progressively interfere with personal liberties and private businesses.
Simultaneous crises could cascade into one another, building up to a point that could overwhelm otherwise long-standing institutions, impeding their ability to maintain order, stability and prosperity.
The best way to prevent a decline in Western economies and societies is to address their unsustainable fiscal, economic, political, demographic and social imbalances, which are increasing. This would require a greater awareness of the problems and crises looming on the horizon.
Currently, public sectors in many Western economies and societies are overburdened and are producing diminishing returns for the resources invested. If such a situation were to continue, in a context of rampant inflation and economic stagnation, it would not be surprising if a collapse could one day occur in their welfare state socio-economic system.
