Not really, no.
GM is a victim of the rise of the professional managerial class. This is a big group of know-nothing (mostly) men with fancy-sounding MBAs from top-flight schools. The problem with the MBA, however, is that it's a cocktail degree. It teaches you nothing, qualifies you to do nothing, and further impresses upon its holders the need to put short-term profit above all other concerns.
The result is that the people running GM don't know about, and don't care about, cars. Their company then produces and markets absolute rubbish, and fails to foresee even the most obvious coming market trends. They reward themselves with lavish salaries and bonuses even while they are running the company off of a cliff. And since shareholders in the USA want to be able to hold stock without actually taking part in shareholder meetings, the executives are able to get away with it. It's the stupid leading the blind.
