Piketty argues that no level or structure of inequality is dictated by technology or markets. Every inequality regime depends on a justifying ideology: a set of beliefs about property, borders, education and taxation that makes the distribution seem fair or necessary. Because these regimes are built by political choices, they can be dismantled by other political choices.
Premodern societies, compared chiefly across Europe and India, were organized into three orders: clergy, who supplied spiritual legitimacy; nobility, who supplied security and order; and workers. Each order's privileges were justified by its claimed function for the whole society. Piketty traces how the centralizing state's absorption of security and administrative functions weakened this justification and contributed to the transition toward proprietarian societies.
After winning independence, Haiti was forced in 1825 to pay France a massive indemnity to compensate former slaveowners for their lost 'property.' It carried this debt, which absorbed a large share of national income, into the mid-20th century. The case shows proprietarian ideology treating slaves as property to be compensated, while the enslaved received no compensation for what was taken from them.
Proprietarianism treats existing property rights as sacred, because questioning any holding threatens to unravel the whole order. This fear of a 'Pandora's box' justified compensating slaveowners and resisting land reform and progressive taxation. The result is that past appropriations, however unjust, become frozen into present entitlements.
Since the 1970s–80s, left-wing parties in Western democracies have shifted from representing less-educated workers to representing the highly educated (the 'Brahmin left'), while right-wing parties have continued to represent the highly wealthy and high earners (the 'merchant right'). Piketty argues that this multiple-elite party system leaves lower-income, less-educated voters poorly represented. In some contexts this has opened space for nativist identity politics.
Piketty proposes making property temporary and circulating. His mechanisms are steeply progressive annual taxes on wealth, reaching up to 90% on billionaire fortunes; a universal capital endowment funded by those taxes and paid to every young adult; and codetermination, which gives workers up to half the board seats and caps any single shareholder's voting power in large firms. Together these limit how far wealth and power can concentrate across generations.
