The liberal policies meant to redistribute income tend to cause that stagnation by choking off private-sector growth, over regulating businesses, and encouraging people to flee the state. That, in turn keeps wages down, hurting middle- and lower-class families far more than the rich.That's happening at the national level, which, under President Obama's policies, has seen stagnant wages and rising inequality. Now if only our president would learn this valuable lesson, we could see greater prosperity up and down the income ladder.
