Moonbattery: Bar Stool Economics: How Taxes Work: "The crazy chart from the commies at Mother Jones he refers to can be seen here.
Basically, moonbats want an economic system in which the energetic and able are enslaved to a nonproductive parasite class. One problem is that people forced to work not for their own benefit but for the benefit of hostile freeloaders aren't as productive. The closer America comes to the communism our rulers are incrementally imposing, the less productive the slaves will be, until we reach the point that they aren't willing or able to produce anything at all. Then there will be no drinks for anybody, and utopian equality will have been achieved at last."
