I was a kid during the GM / Auto industry bailout in '08 but I am struggling to understand why the government is meddling in the stock market if it's not a bailout of a to big to fail company. If that's the truth, why is public opinion and faith in big AI not shifting the way Americans began to distrust the automotive industry post '08 bailout? I'm just a bro so be nice if this is a dumb question.
