Over the past century, capitalism and liberal democracy have defined the global economic and political order. Together, they promised efficiency, prosperity, and freedom. They were expected to reinforce one another: capitalism would drive growth, and growth would nurture democracy. For much of the twentieth century, this vision seemed to hold.
Yet today we find ourselves in a very different place. Despite immense technological advances and unprecedented global wealth, the system shows deep fractures. Rising inequality, political disenchantment, slow growth, and environmental strain have become defining features of the present. To understand our moment, we must confront not only the achievements of capitalism and democracy, but also their side effects and fragilities.
Where We Are Now
After a century of capitalism, the global economy and society exhibit a paradoxical mix of prosperity and precarity:
- High income and wealth inequality, echoing Piketty’s observation that returns on capital (r) outpace economic growth (g), concentrating wealth in fewer hands.
- Ageing populations and high dependency ratios in advanced economies, creating pressure on public finances and social safety nets.
- Disenchantment with governments, in line with Rodrik’s thesis that globalization has outpaced the capacity of national democracies to deliver.
- High and rising public debt, as states borrow heavily to sustain growth, cushion crises, and meet welfare commitments.
- Sluggish economic growth.
- High asset growth, enriching capital holders while leaving wage earners behind.
- Persistently falling interest rates, a symptom of what Larry Summers has termed “secular stagnation.”
- Rising global temperatures and climate volatility.
The Promise of Capitalism and Liberal Democracy
Capitalism was built on the principle of allocative efficiency: markets reward innovation, discipline inefficiency, and maximize growth. Joseph Schumpeter famously described this as creative destruction, the process by which innovation drives long-run prosperity. Liberal democracy, in turn, was expected to flourish under prosperity. Rising incomes would generate a broad middle class, the supposed foundation of stable democratic societies.
For decades, this model appeared successful. Postwar growth lifted millions out of poverty, rebuilt war-torn economies, and spread democratic institutions. Capitalism and liberal democracy reinforced each other, producing stability and dynamism.
The Side Effects of Success
Yet the very mechanisms that fueled growth also generated imbalances:
- Concentration of wealth: As Piketty argues, when capital returns exceed growth, wealth inevitably accumulates faster than wages.
- Erosion of labour’s share: With globalization and automation, labour increasingly loses bargaining power, a trend foreshadowed by Marx’s prediction of capital’s dominance over wage labour.
- Persistent inequality: Across generations, unequal gains compound.
- Over-saving and under-consumption: Keynes noted that excessive saving by the wealthy can lead to a paradox of thrift, depressing aggregate demand.
- Disinflation and stagnation: Inequality itself becomes a drag on growth, locking economies into sub-par performance.
- Misallocation of resources: Abundant savings chase speculative returns, inflating asset bubbles rather than funding productive investment.
- Falling interest rates and rising debt: To compensate for weak demand, states and households borrow more, deepening dependence on cheap credit.
These side effects are not incidental. They are intrinsic to the dynamics of capitalism in its current form, where returns to knowledge and capital systematically outpace returns to labour.
Fragilities in the System
The contradictions of capitalism and liberal democracy are tolerable — until they are not. Several pressure points reveal the fragility beneath the surface.
Inequality can be sustained until:
- Inflation and living costs rise enough to expose disparities (a recurring theme in Polanyi’s Great Transformation).
- States visibly fail to deliver promised public goods.
- Social media amplifies resentment through constant comparison, magnifying the visibility of inequality.
- Populist leaders harness discontent, as described in recent political economy analyses of democratic backsliding.
Low interest rates are sustainable until:
- Public debt exceeds credible thresholds of repayment.
- Inflation becomes entrenched above central bank targets.
- Central banks lose credibility in their ability to monetize debt.
- Demographic shifts reduce savings, reversing the long decline in rates.
- Investors lose confidence in the fiscal capacity of states.
Sovereign bond markets remain calm until:
- Confidence in government solvency falters.
- Hyperinflation emerges, often triggered by a loss of trust in the state.
- Severe supply shocks ignite sustained inflation.
- A subset of countries’ debts spiral out of control, though systemic crises typically require broader distress.
Conclusion
A hundred years of capitalism has brought both extraordinary prosperity and deep systemic tension. The same system that raised living standards and spread democracy now generates inequality, stagnation, and disillusionment. Its fragilities are not abstract: they reveal themselves when inflation bites, when governments overpromise and underdeliver, and when trust in institutions erodes.
Capitalism and liberal democracy have not failed outright, but they are failing to adapt. Without rebalancing — through policies that spread knowledge, broaden opportunity, and address externalities like climate change — the system’s contradictions threaten its own survival.
Markets left unmoored from society’s needs will eventually provoke backlash. Unchecked inequality depresses demand and undermines growth. Capital’s logic tends toward concentration unless restrained.
The question is not whether capitalism can generate wealth. It is whether capitalism and liberal democracy, as currently structured, can sustain legitimacy in the face of their side effects. The answer will determine whether the next hundred years bring renewal — or rupture.
