The problems have not gone unrecognized and heroic measures have been undertaken, but technocratic reforms from within have not changed the culture. Technocratic reforms from Washington won’t either. For the elemental facts about the Obama restructuring plan are these: Bureaucratically, the plan is smart. Financially, it is tough-minded. But when it comes to the corporate culture that is at the core of G.M.’s woes, the Obama approach is strangely oblivious. The Obama plan won’t revolutionize G.M.’s corporate culture. It could make things worse…

The end result is that G.M. will not become more like successful car companies. It will become less like them. The federal merger will not accelerate the company’s viability. It will impede it. We’ve seen this before, albeit in different context: An overconfident government throws itself into a dysfunctional culture it doesn’t really understand. The result is quagmire. The costs escalate. There is no exit strategy.
