Jobs have gone elsewhere because costs are lower and efficiency greater overseas

No.

Jobs have gone elsewhere because a decent profit and a fair return on investment are no longer sufficient for the greedy bastards who pine for the days of The Gilded Age and wish they were J.P. Morgan - now they must make an obscene profit, and damn the consequences.

And also because these 'job producing patriots' don't really give a fuck about the USA or US workers as long as they keep making gobs of money - by any means necessary.
