TL;DR

The paper argues that the global financial crisis since 2007 stems from a systemic delusion in policies based on a 'perpetual money machine'—an unsustainable model of growth fueled by debt, financial profits, and asset bubbles rather than productivity. It traces the shift from post-WWII productivity-driven growth to rent-seeking and speculative finance, showing how deregulation and financial innovation amplified systemic risk, leading to recurring crises.

ABSTRACT

We argue that the present crisis and stalling economy continuing since 2007 are rooted in the delusionary belief in policies based on a "perpetual money machine" type of thinking. We document strong evidence that, since the early 1980s, consumption has been increasingly funded by smaller savings, booming financial profits, wealth extracted from house price appreciation and explosive debt. This is in stark contrast with the productivity-fueled growth that was seen in the 1950s and 1960s. This transition, starting in the early 1980s, was further supported by a climate of deregulation and a massive growth in financial derivatives designed to spread and diversify the risks globally. The result has been a succession of bubbles and crashes, including the worldwide stock market bubble and great crash of October 1987, the savings and loans crisis of the 1980s, the burst in 1991 of the enormous Japanese real estate and stock market bubbles, the emerging markets bubbles and crashes in 1994 and 1997, the LTCM crisis of 1998, the dotcom bubble bursting in 2000, the recent house price bubbles, the financialization bubble via special investment vehicles, the stock market bubble, the commodity and oil bubbles and the debt bubbles, all developing jointly and feeding on each other. Rather than still hoping that real wealth will come out of money creation, we need fundamentally new ways of thinking. In uncertain times, it is essential, more than ever, to think in scenarios: what can happen in the future, and, what would be the effect on your wealth and capital? How can you protect against adverse scenarios? We thus end by examining the question "what can we do?" from the macro level, discussing the fundamental issue of incentives and of constructing and predicting scenarios as well as developing investment insights.

Motivation & Objective

• To expose the flawed economic model that equates money creation with real wealth generation.
• To document the historical shift from productivity-driven growth (1950s–1960s) to debt- and speculation-based expansion since the early 1980s.
• To analyze how financial deregulation and innovation in derivatives amplified systemic risk and enabled interconnected bubbles.
• To challenge the assumption that monetary policy alone can sustain long-term economic stability.
• To advocate for scenario-based thinking and structural reforms in incentives to prevent future crises.

Proposed method

• Analyzes macroeconomic data from 1950 to 2012 to compare savings, investment, and financial profits across growth regimes.
• Traces the evolution of financial innovation, particularly derivatives and special investment vehicles, as risk-spreading mechanisms that instead enabled leverage and contagion.
• Identifies recurring financial bubbles (e.g., 1987, 1990s Japan, dotcom, housing, commodities) as symptoms of a systemic structural flaw.
• Uses historical case studies to illustrate how policy responses based on money creation perpetuate the illusion of endless growth.
• Proposes scenario analysis as a framework for stress-testing portfolios and economic policies under adverse conditions.
• Emphasizes the need for new institutional incentives that align private incentives with long-term systemic stability.

Experimental results

Research questions

• RQ1 What structural economic shifts since the early 1980s have replaced productivity growth with financial engineering and debt expansion?
• RQ2 How did deregulation and financial innovation contribute to the proliferation of interconnected financial bubbles?
• RQ3 Why do repeated policy responses based on money creation fail to resolve underlying economic imbalances?
• RQ4 What role do asset price bubbles and financial profits play in distorting real wealth creation?
• RQ5 How can scenario-based analysis improve resilience to systemic financial risks in uncertain environments?

Key findings

• Since the early 1980s, consumption growth has increasingly relied on shrinking savings, rising financial profits, and wealth extraction via house price appreciation, not productivity gains.
• The transition from productivity-driven to finance-driven growth coincided with deregulation and explosive growth in financial derivatives, increasing systemic risk.
• A sequence of interconnected bubbles—including equity, real estate, commodities, and debt—has emerged since the 1980s, each feeding on the prior one’s excess liquidity.
• The 1987 stock market crash, the 1990s Japanese bubble burst, the 1994–1997 emerging market crises, LTCM, the dotcom crash, and the 2008 crisis all reflect the same underlying flaw: reliance on monetary expansion over real investment.
• The paper concludes that continued faith in a 'perpetual money machine' is economically unsustainable and that scenario-based risk assessment is essential for future economic resilience.
