Wealthy people aren't putting money into the market atm- they're taking it out. It's called flight to liquidity. Many institutional investors are doing the same, in no small part because of the risk of counterparty default in the derivatives market.
Income redistribution is one of the prominent features of any modern, mature and wealthy mixed economy, and has been for decades. Get used to it, or move some place like Somalia. It takes a variety of forms, from labor unions to progressive taxes to subsidies for low end employers in the form of EIC or similar. Without it, we'd have degenerated into a plutocracy and a lower (much lower) two class society. Lords and Serfs. Patrones and Peons. Pick your language, it's the same deal.
Sometimes this redistribution occurs openly, and sometimes more stealthily. Sometimes it's honest, sometimes it's not. Governmental debt is a stealth method, and a dishonest one, because it redistributes income from the future to today. It's also a deception on the level of who'll be sticking around to pay the debt in the future, as well. Modern wealth is quite portable, and citizenship largely an issue of convenience for those who have it.
Trickledown economics are an expression of that basic deception. In reducing the redistribution of today's income, some substitution has to be made to provide the illusion of it, and deficits do that rather effectively, at least for awhile. When push comes to shove, it turns out that the govt is so far in debt to the world's wealthiest citizens that the govt is powerless, and must debase the currency, the citizenry, or both in order to pay the rent, the interest on the debt... Recovery is difficult, because investment in the productive capacity of the target economy has been removed, recapitalized elsewhere in the world with the largesse of taxbreaks for those at the top.
Trickledown can't be sold w/o huge deficits, simply because the electorate won't be content to watch the rich get richer as they get poorer paying for all the things that protect and concentrate wealth and privilege...
