2019: That bond bailout you didn't hear about
2020: COVID bailout
2022: Various credit/liquidity facilities and the slow-walked rate hikes

The boom-and-bust cycle is a natural consequence of running an economy on debt: margin leads to speculation which leads to overheating, and then it has to cool off. It is entirely possible to guarantee the public's welfare during busts; you just have to sacrifice not having a ceiling on earnings/wealth.
