"Free" trade only works when both trading partners are on equal status. Tariffs were established to balance the equity. The reality is, labor jobs have been shifted to countries with no environmental laws, no labor laws, no intellectual property laws, and government paid health care. When rational people say, "um, wait a minute, that's not fair to American workers", some oligarchy puppet screams "you're against globalism, fair trade, against jobs and a racist!".
Sorry, that's all b.s.. The TPP is a payoff to the rich for their support of Government elected minions. The only way to fix this is get money out of politics.
