There's not much recent history of particular consequence facing for this sort of thing in the United States, financially or politically. It's not like we locked up bankers after the housing bubble collapsed or punished people for lying us into Middle Eastern wars.

I have a hard time pinning down when we stopped handing out actual sentencing for stuff like this. Nixon walked after Watergate, but at least the fall guys get hit with (some) time. Reagan walked after Iran-Contra (grand treason by the way), but his fall guys also walked. Even moving away from unitary executive talking points, like you said nothing really happened to the 07-09 gang, midlevel analysts got pinched for manipulating LIBOR, I'm trying to think about the last time there was proper consequences, IIRC most of the big wigs at Enron pled guilty, and it turned the big five into the big four. Maybe SBF? Even then, that was one guy catching several dozen people's utter carelessness and EA fueled mania.

I really would love to figure out when we phase shifted into this mode, maybe it was always like this, I'm frankly too young to have anything else to compare to.
