Where do you think the Federal Reserve is getting the trillions it is spending to buy up crappy loans and Treasuries? Do you think it was just sitting on ~$1.2trillion, doing nothing with it? No, it printed it. Well, it decided that its accounts, (electronic) had an extra trillion or two, then spent it. Seeing as it controls the supply of money, it can do that. That money went to things like government bonds, which then was spent on REALLY expensive stimulus jobs or ‘infrastructure’ spending, and worked its way into the economy. Eventually it will have to be pulled out, or risk really high inflation, but that is a story for another day/year. RIght now it gives us a nice sugar high.
