Not all of it at all. Once again, we have a perfectly healthy manufacturing sector here in the US it just isn't as labor intensive at it used to be because. . . labor is more expensive. That isn't something to fear. I also find your apparent desire for people to remain locked into low paying crappy jobs somewhat disconcerting. Why shouldn't we desire better than that and evolve towards that desire economically? Eventually as labor in the rest of the third world increases they will substitute labor for capital investments in these areas. There is nothing bad about that, it frees labor up to engage in other pursuits and skill sets and frees them up to innovate.
The problem with your statement is that manufacturing here isn't the main source, of well.. Name one. Yeah, labor is expensive, **** paying people fairly, capitalist pigs have known this for years, thanks for the news. I don't want people to remain in low paying jobs, I don't want them to essentially be put into wage slavery and be exploited by greedy pigs who know better. Remember the tragedies that keep happening in Bangladesh? Good Regulations apparently hurt capitalist profits, hm, another contradiction. Substitute labor? How do you propose these people keep jobs then? Unless we go towards a massive welfare state, which would be cool I guess.
