No, I would not have done the same things GM did after the war. I don't have to eat everything on the table to be full. There was enough business to go well around after the war; there was no need but unbridled greed to destroy competing (and dare I say) "more future friendly" enterprises. What is good for GM is not and never was what was good for America. Ask Flint Michigan and and Monterey Mexico where GM's alliences lie.
Henry Ford's political and and social views may well be bigoted and wrong minded, but at least he held them for no other reason than that was what he really believed was best for the nation, GM never was and never will be anything but GREED MINDED.
For my part, I wish Ford was still running the show;at least he was interested in America as a whole and not just place to peddle cars.
And, to keep things on topic, he saved a former Grant narrow guage Texas and StLouis (36") mogul and converted it to standard guage about 1925 or so.
Fellow named Frank Coyne had it in south Texas after its sale from Greenfield Village, now its in Illinois.
