It accomplished that by offering yet another apocalyptic vision of capitalism in the tradition of Malthus, Ricardo and Marx. To American workers and a middle class besieged by stagnant wages and rising taxes, it provides justification for the dangerous elixir of confiscatory taxes on the wealthy hustled by liberal pundits and politicians.
Examining an incredible range of data across many countries and several centuries, the author purports to demonstrate that over time capitalist economies naturally concentrate ever greater shares of wealth and income into the hands of a few, leaving less resources to pay the wages of ordinary workers.
The theoretical mechanics of his assertions are as arcane as classical physics and only an economist could reasonably divine their weakness. Still, Piketty's answers to income inequality are remarkably seductive. He proposes an 80% tax on incomes over $500,000 or $1 million and an annual levy on wealth of as much as 10%.
In turn, the revenue raised could finance more redistribution programs, championed by progressive politicians seeking votes, such as state-subsidized health care and superfluous government jobs.
Without those taxes, Piketty asserts society will become ever more stratified and hard work will become futile. The best and brightest among those not born to great wealth, like characters in a 19th century novel, will conclude that marrying a fortune is a much better life strategy than seeking gainful employment. All of that will kill economic growth and make ordinary people poorer.
Piketty argues the ever greater concentration of wealth continued into the 1920s, when disparities between rich and poor reached a peak. It was only the disruptions of two world wars and the Great Depression that destroyed much of the capital concentrated in the hands of the wealthy and permitted the post-World War II prosperity and rise of the middle class.
Now, Piketty argues, the forces driving inequality have reemerged. We live in another Great Gatsby era with Wall Street barons earning in the millions while workers toil at Manhattan restaurants for barely more than the minimum wage. Piketty's model of capitalism is tight and compelling because of what it ignores.
