The machines aren't the problem, they have to be serviced and maintained. The problem with employment in America is unpatriotic bastards moving jobs overseas and bringing in foreign workers while enjoying the benefits of the USA. It seems patriotism is only for the little people.

For it is not the wolf or any of the other beasts that would join the contest in any noble danger, but rather a good man. Aristotle, Politics, Book IIX
