Apparently the OP doesn't know what stagflation is. Go take a look at the 1970s and educate yourself.
Printing dollars keeps their value in step with the growth of the world which uses it as the reserve currency. When you print far more than the growing global popution needs, you have a problem for a number of years until the global economy grows into the glut in supply. And many other things beyond most Amercians who don't realise how the US swings from being at best symbiotic to parasitic in a crisis and has a free lunch that small nations don't ever get.
