Does anyone remember what the government did to help out Harley-Davidson back in the mid 80's? They put a tariff on imported motorcycles over 700ccs. That, plus the fact that the company is employee owned and not unionized, gave the company a little breathing room to get its ass back into shape. Now Harleys are coveted throughout the world.
I'm not sure what the government can do for GM, but it sure as heck must involve getting rid of the current union system, and it doesn't have to involve "bail out" with huge amounts of cash. That will only postpone the otherwise inevitable.
they could force the foreign companies to unionize.
they could impose tariffs on cars coming into this nation.
They could demand that cars built here were build from parts made here.
In other words, they could start being economic nationalists like made this nation great in its first 200 years.
