All of the companies you listed were started by American individuals with minimal budgets. So I ask you, why don't you go out and do the same? Why complain and wait for someone else to do it? I don't mean to criticize you, I am just asking it as a rhetorical question. Maybe the reason all those companies are American ones is because there is an American mentality that is different than that of Europeans. Everyone in the USA is dreaming about how to start more companies like that every day.

Also, Europe has good car companies. VAG is on top, for one. I don't know why they bought Ducati, but I guess they can because they are on top. Just because GM left Saab to die you should not be disappointed.
