Thomas Piketty's book Capital in the 21st Century was such a massive bestseller that it was ranked #1 on Amazon.com. At one point, Amazon, the largest bookstore in the history of the world, ran out of copies for days. The book included statements like “When a government taxes a certain level of income or inheritance at a rate of 70 or 80 percent, the primary goal is obviously not to raise additional revenue (because these very high brackets never yield much). It is rather to put an end to such incomes and large estates.” Like Marx, Piketty kinda got caught up on that whole impersonal economic forces thing at the expense of, you know, telling the truth.
