This is the ultimate problem with "trickle down" economics. Capital doesn't drive growth. Lack of capital limits growth, but excess capital doesn't generate additional growth. Demand drives growth and 35 years of stagnant wages (wages are basically where they were in 1981) have put a chokehold on growth.
This is why you have the seemingly incongruous effect of high taxes encouraging growth and low taxes stifling it. Ultimately "high taxes" tend to effect the rich a lot more than the poor, and the money ends up being redistributed somewhat equally, spurring demand as the poor can suddenly afford a lot more good and services.
