There’s no where left go after this.
First thoughts: Japan, Inflation… and holy shit.
Even if this (the Fed and Treasury plan) works and keeps us out of a severe depression, which is the goal and, likely, the result, we are going to have long, long hangover.
Where are all these dollars gonna go? And how, in the long run, are they going to maintain their value?
Just remember, ultimately, a loose monetary policy is what caused this mess in the first place.
