So far the money printing hasn’t shown up as inflation here in the US.
Part of that is the decrease in the velocity of money. As long as inflation is very low, you can afford to sit on cash. But if we do see inflation or a continued fall in the dollar, that money will run from cash dollars, increasing velocity and providing positive feedback.
We are now in a truly global economy. Money printed here doesn’t stay here. It causes inflation world wide. Google China and “hot money”. This is also why stimulus money won’t work effectively anymore. Instead of stimulating the US, money just pours into Asia.
