They call it QE, quantitative easing, to obscure the fact they are printing trillions of dollars from nothing. No one studies this, so no one understands that it is counterfeit currency not even really money. But they are duped into thinking real money like bitcoin and gold are not. Hardly anyone even understands enough Econ 101 to know that any time you increase the supply of a good you decrease its value.
Uh, quantitative easing is the buying of US bonds, to get investors to invest in and spur the economy, and not the printing trillions of dollars. It's the earnings from the investments made that are put back into the economy by the Fed.
Lots of people study this and it was very easy to look up. The people who do study this are called economists.
All the best,
