[...] if all people owned an equal amount of wealth, all of them would equally profit from a strong growth of capital. In fact, however, wealth is unequally distributed, according to Piketty. He does not explain why that is. Rather, he assumes inequality as a given, and examines its development over time. This demonstrates, according to Piketty, that the strong growth of wealth in contrast to that of income exacerbates an inequality characteristic of all societies: those who have, receive (more). The rich become richer. According to Piketty, increasingly inequality is not a coincidence, but rather inscribed into economic development. Piketty says this is the case not only under capitalism, but also in other economic forms. However, Piketty does not wish for this diagnosis of growing inequality to be understood as a call to class struggle: ‘To be clear, my purpose here is not to plead the case of workers against owners but rather to gain as clear as possible a view of reality.’

[...] Only a few years afterwards, however, it underwent a drastic reduction. One reason for this was of course the loss of wealth in the form of ‘war damages’. A further reason was the devaluation of financial wealth in the form of government bonds: government bonds were already held in the eighteenth and nineteenth centuries, but in the course of war financing from 1914 on, their importance increased. After the First World War, these assets were devalued by inflation. In order to minimize the effects of inflation upon the general public and curb the price spiral, rent controls were also introduced, which reduced the returns on real estate. And finally, in their financial need, governments decided upon higher taxes upon inheritance and top incomes, which further eroded wealth – at least in France, Germany, Britain and the US.

This taxation was something new. Before the war ‘tax rates, even on the most astronomical incomes, remained extremely low … This was true everywhere, without exception.’

Hidden behind these pure numbers, however, are radical changes within society. According to Piketty, states used their tax revenues in order to build welfare state structures. With the loss of significance of the super-rich, and a new relation between the state and the market, a new middle class emerged that could build up wealth by means of its labour-power and income. The emergence of this middle class was the result of the decline of the capital–income ratio. [...]

Piketty’s central point of critique is aimed at the legitimation of inequality. Bourgeois society’s self-description, in which inequality is a consequence of different abilities, will no longer be accurate in the future. To make a long story short: effort will no longer be worth it.
