Kevin Drum's piece on the decline of labor unions and the rise of corporate power is excellent and definitely worth a read.

Millionaires pay less than a third of their marginal income in taxes, and somehow they've convinced a fair share of Americans that they're overburdened and overtaxed. It's amazing.
