After GM died and a new company was created much of the former problems have vaporized and noone really knows what GM is anymore.
GM does not have any obligations toward former employees and former sharholders and management is pretty much out of the picture.
GM seems to be doing best in China and the biggest car market is now in China.
So the question is if future GM will be based in China with some connection with USA.
Similar moves has happened with other big US corporations.
