Congress could give the Fed the power to, rather than just buy bonds (or whatever it is they do) introduce money to the economy simply by giving everyone money.
I understand that it is not exactly true that the rich are getting free money for nothing. But the whole reason we're talking about this here is that someone pointed out that all the new money supply from the Fed is finding its way straight to people and corporations that don't have anything better to do with it than buy assets, the prices of which continue to grow as a result, even while the GDP rate is plummeting.
Lastly, I'm totally open to the idea that someone will come along and explain to me why my idea for how the Fed should give everyone money is just not workable. If that happens, I'll be happy to have learned something useful. But it's definitely not clear to me, a priori, why it wouldn't work if it wouldn't.
