I live here and come from a GM family. You have exactly nailed it. Every aspect. I commend you. Others read what he said. But it is solvable with a lot of pain. More pain if they go bankrupt
Thanks for the compliment.
One other point I wanted to make, but the post was getting too long. Auto assembly is almost uniquely vulnerable to strikes because of just-in-time. Detroit needed to switch to JIT to be competitive with the transplants.
But JIT gives the most self destructive morons in the chain the ability to shut down the entire operation. (see Americal Axle strike).
GM parts suppliers are much more heavily unionized with UAW locals that are more militant and brain-dead (again see American Axle strike).
Any turnaround for GM has to deal with the UAW issue for both GM and it’s suppliers. Either a no strike contract, or better yet, get them out of there.
