Is the marriage between liberal democracy and global capitalism an enduring one? Political developments across the west — particularly the candidacy of an authoritarian populist for the presidency of the most important democracy — heighten the importance of this question. One cannot take for granted the success of the political and economic systems that guide the western world and have been a force of attraction for much of the rest for four decades. The question then arises: if not these, what?

A natural connection exists between liberal democracy — the combination of universal suffrage with entrenched civil and personal rights — and capitalism, the right to buy and sell goods, services, capital and one’s own labour freely. They share the belief that people should make their own choices as individuals and as citizens. Democracy and capitalism share the assumption that people are entitled to exercise agency. Humans must be viewed as agents, not just as objects of other people’s power.

Yet it is also easy to identify tensions between democracy and capitalism. Democracy is egalitarian. Capitalism is inegalitarian, at least in terms of outcomes. If the economy flounders, the majority might choose authoritarianism, as in the 1930s. If economic outcomes become too unequal, the rich might turn democracy into plutocracy.
