You obviously do not understand capitalism. An American company so badly mismanaged SHOULD fail. The failure of GM will trigger a much better use of capital and assets. That's how things GET BETTER AND GROW under capitalism.
Investors understand what a dying dog looks like.
Clinging to something once successful but now failed is in NOBODY'S best interest.
Yeah, just like it did with bad American steel companies, right?
The real, core problem with the auto industry is very simple: Unions. Unless the UAW and all that comes with them are eliminated, no American car manufacturer will ever survive, regardless of what else is done with capital and assets.
