What the bankers learned in 2008 is that if you make risky bets with a large enough pile of money, the US federal government will backstop your losses, ensure you can pay out your executive bonuses, and keep your depositors whole. You can even fabricate documents and break a raft of laws, and as long as you bribe the right politicians, you won't even get in trouble. It's the entire rest of the world that will get fucked, not you, personally. I guess 2023 is when we test whether or not that was a one-off or a permanent rule (it's a permanent rule).
