"practically giving one group of people money, under the guise of stimulating AN economy."

It wasn't under the guise of anything but saving the US economy from a wicked meltdown of epic proportions.

The dominos were set to all go down, the Fed kept a few of them up by rebalancing wealth.

As you point out - viciously unfair - but better in the long run.

FYI - a 'strict currency' is perhaps worse; crisis will happen. Strict currencies ties our boat to the dock, too much or too little water and we're all smoked. Moreover - outside of crises, the economy is dynamic - growing and shrinking, monetary policy helps manage that.

A strict currency is better than a poorly managed currency, but a well managed currency is better than a strict currency.
