What happened to GM? It used to be said that “what’s good for GM is good for America” (actually, it was a rather arrogant former CEO of GM who said it but I don’t have the time to mythbust). Of course, now it seems that GM is just symptomatic of everything that has gone wrong with America over the past 50 years. Is there a chance things at GM could turn around? Is there a chance they can re-learn all the leadership lessons they once taught the world? In what I think is an incredibly detailed, informative and concise video, Fortune’s senior editor at large Alex Taylor III not only breaks down the last 50 years at GM and also gives us a peek into what might be a much brighter future.
