When you said "如果降低工資成本，一紙文件一夜之間就可立即完全解決問題", I am not sure you know what you are talking about. You think GM/FORD/Crysler can reduce salary at will? Get real first.

UAW has been the most powerful union in US. Auto workers has contracts with the company and they are protected. On top of that, they can go on strike legally when they choose to.

The only way the the Big 3 to survive may be to declare bankruptcy so they can nullify the union contract. After that, they can renegociate the salary with workers.

Currently, the average labor cost at Big 3 is about $73/hour compared to $47/hour at Toyota, and there is no union at Toyota. 'Nuff said.
