Your assuming things that are not necessarily the case. GM had some terrible factory's in the 80's where you could buy alcohol, hard drugs, and visit a prostitute all inside the factory. That has little to due with the US work force and a lot to due with the history of Union activity at GM.
I do not doubt that some executive in the American auto industry JUST TODAY used hard drugs and alcohol in the office. The prostitution probably happened in a hotel somewhere, the accommodations paid with frequent flyer miles.
