Oldsmobile stopped production in 2004....
And UAW is far from small.
Most automakers traditionally shut down the weeks of Christmas and New Years. This year they are just extending those shut downs to save cash and catch up with inventory.
I think the main problem is that US automakers are not making what most consumers want these days. People STILL see American autos as less reliable, less efficient and less value for money than the foreign brand cars. I don't say foreign made because most of them are made in North America despite the badge. The US needs to offer efficient, well priced cars that are stylish and different like the foreign maker cars.
The US also put all of it's eggs in one basket. We all know how that saying goes. They relied on trucks trucks and trucks and didn't diversify and prepare for changing times.
