DAVID HARSANYI: What Thomas Piketty's popularity tells us about the liberal press. Inequality is growing. Mobility is shrinking. Meritocracy is dead. We all live in a sprawling zero-sum fallacy. So we must embrace redistribution on a massive scale.

I’d ask if there are any historical examples that prove that skewed wealth in a generally prosperous nation is more damaging to its democratic institutions than the reallocation of wealth by a coercive state. But then I realize, as with any Marxist revival, the answer is: This time we’re gonna do it right!

Think Cuba. And Venezuela.
