No wonder there is a backlash against globalism and 'free trade' agreements when this same group of insular regulators and powerful market leaders are designing the agreements and calling all of the shots. Sweatshops are hardly the result of free trade but government controlled/financed trade that only prioritizes the interests of the mega corps, sometimes pushed to the point of exploitation in countries with poor legal systems and weak concepts of human rights.
The process of creating the TPP made this even more apparent to the public, they hardly even tried to hide the obvious favoritism and complete lack of openness. Clearly it has become so status quo that they didn't even bother with pretense.
