If the government seizes control of a major industry, that’s a lot of power and opportunity for politicians. It’s already been done in some local areas, and it had the broad support of the people because “the electric company is gouging us, the gov should take it over” is an easy sell.
I just don’t think it’s feasible at a federal level. Or even for some states (Newsom refusing to do anything about SDGE comes to mind) It’s so easy to cry socialism about this topic too.
I also think there might be a disconnect between government power and politician power.
