If we're going to have trickle-up economics, where money inevitably ends up in the hands of the richest among us because large amounts of capital in one place seem to exert an almost gravitational pull, then I think it makes sense to use the government and its powers of taxation as a countervailing force by taking money from the rich and either pulling it out of circulation permanently or redistributing it to the working class, who will in turn spend it on goods and services so that this money eventually finds its way back to the rich.
