Is the (auto) market in trouble? No.
Just the big 3 are.
Why? Because they make product that is less in demand and because they have unfunded pension liabilities stemming from them being negotiated by unions ages ago.
Were they to fail (and realistically only 1 would fail and the other 2 would eat a lot of the "failure's" domestic market share), then as the auto market is healthy enough, customers would buy elsewhere and jobs would be created there.
Don't you drive a german car? If you want to save their jobs then buy one of the Big 3's cars. You won't because you'd rather not spend your money on them so WHY would you spend your tax money on them?
"There can be no freedom without freedom to fail." – Eric Hoffer (1902-1983), The Ordeal of Change, 1964
