Let 'em go into chapter 11.
Until the Detroit-3 reorganize their processes and jettison the unions, they are not going to be able to compete. I have a Japanese make SUV. The American models just didn't stack up, same HP/lower fuel mileage, service/mileage, chassis and powertrain, and cost.
If you automatically have a $4,000 mark up on your vehicle, to pay the union and it's pension, versus it's competition in the same class guess what is going to happen. If your vehicle will not last as long, or look as good, or resale as well as the competition, you lose.
Americans can make cars, and we do, they are made in Tennessee, Kentucky, Alabama, Texas, North Carolina, and Missouri. Of course they are all "foreign" makes. My last car was a Celica. Comparing it directly to a Mustang was a sheer surprise to me. It had better take-off and braking, the Celica's cornering was vastly superior to the Mustang. It was also more American than the Mustang.
(Mostly just my rant.)
