That's been the primary impact of NAFTA and all the much ballyhooed major trade deals: lower or eliminate tariffs on exports to the US, lower barriers to investment in cheap labor nations, and thus increase incentives and decrease disincentives for US firms to relocate manufacturing facilities and jobs to cheap labor nations, and then export products back to the US tariff free, or almost tariff free.
And then we have higher trade deficits and fewer manufacturing jobs for Americans and more Americans signing up for the myriad of government poverty programs. Works every time and it will work again with TPP.
Worth repeating. Free traitors would have us believe that corporations only do this to benefit the US consumer. Meme: The corporation do not profit form this at all, they do it out of a sense of altruism. Doesn't effect their bottom line, it just makes thing more affordable to the US consumer. Yeah right.
In 1993 I saw Bob Dole and Bill Clinton stand together and celebrate the passing of NAFTA by one vote...Gore broke the tie. I said to anyone who would listen “When Dole and Clinton agree, it can’t be good for us.”
