Does it occur to you that maybe people keep saying this because that's the truth?
I think it suffices to say that at least for the COVID round in the US, the "money printing" was in the form of the Fed buying US treasuries and the US government paying out trillions of dollars to normal people in the form of COVID stimulus checks. Yes, a significant part of it directly went to normal people, and it wasn't in the form of commercial banks lending money out.
You're advised to look at the Fed balance sheet, covid stimulus checks, the market cap of big tech, and the flow of speculative money (VC capital [or startup valuations], BTC, GME, etc.), especially with respect to the dates and timings.
If you think you learned everything you need to know about economics from some 10+ year old textbook, let me give you an update: in the US there's no "fractional reserve banking" system any more, unless the "fraction" is zero. Basically it's QE all the way now. ( https://www.federalreserve.gov/monetarypolicy/reservereq.htm )
