"ok, theoretically, lets say the US government did not bail out any companies,"
ok.
"multiple banks went bankrupt,"
We are not talking about the financial institutions. Thats a complete different story.
"GM and chrysler at least went bankrupt"
Yep. As they should.
"millions more people lose their jobs" "then they did, car part manufacuers go bankrupt with GM and Chrysler gone,"
That is two times a giant jump to conclusion I disagree with. What would have happened? someone would have bought those companies or pieces of it. If nobody was able to pay much, it would have gone cheap but what is the problem with that? The debts of those companies would have been gone. So the only difference would be that there would be another management then one that has proven its incapability. Some people might have lost there jobs. But the gov could give a very small bonus to the new owner if he wouldn't fire them all at once. That bonus is very little compared to buying up the entire company.
What happened now? The same people who are responsible for the crash - partially because they give themselves to much cash from their own company, partially because they are incompetent - are allowed to continue with tax payers money. That's insane.
