> ...governments don't know how to mandate good corporate governance...

For a very brief moment, under the existential crisis condition of total war in WW2, the US government was somehow able to corral corporate governance towards a semblance of common purpose (survival). As I understand it from historians malfeasance was still widespread, but we arguably maybe got a good enough outcome?

This is the corporate equivalent of the shirtsleeves to shirtsleeves in three generations problem. And if that corollary is true, then I suspect the remedy is similarly not entirely amenable to deterministic antiseptic metrics and processes; they're necessary but not sufficient conditions.
