I know you know about Moral Hazard. I know you know about small bubbles allowed to get bigger getting out of control. I'm sure you know the phrase "Privatized gains and Socialized losses." These all apply here.
The mark of a successful Fed is in reducing not just the frequency of banking issues but also the amplitudes. Every time the Fed is forced to step in, the interest rate cuts get bigger, the debt they create gets bigger, the Congressional action larger.
The mark of a successful Fed is in stepping in ahead of time before the bubble gets out of control. If a Fed needs to take drastic action, they've already failed. CO-VID, being the first non-financially caused recession in 50 years, is a special case, and for that I give them leniency.
