The problem is you had to know someone that worked at GM to get a job at GM.

I had a family friend that was a union boss and after high school he got his son into GM. The family friend though wasn't going to get me in.

It was huge money at the time but it is also why GM stopped being competitive. I think the union boss friend retired at 45 or something completely ridiculous.

Of course he also had the nicest sports car, a huge boat, a huge house for the time.
