They don't trust the free market and believe it isn't free at all. They see greedy, manipulative robbers out to exploit the working man. They therefore trust government to level the playing field and keep the greedy bastards in check. They mock Adam Smith's "invisible hand" believing the government must move the hand to makes thing fair. Markets have natural cycles of boom and bust. Liberals HATE the bust aspect so they regulate the snot out of the market which also prevents booms. What we get is a stagnant economy ala today with high unemployment and a GDP around 1%. Somehow, that's better than 6-7% followed by a short recession. Go figure.
