The idea that a bill written for global mulch-national corporations is any good for the workers is ridiculous. This along, with other free trade bills such as NAFTA hurt the backs of the working class both in Mexico and the US and only benefit the rich and the corporations. These bills also leads to a more globalized world, not for the workers or the people and communal friendship and peace but for the exploitation of the common man for the 'profit' of private business as well as the destruction of american industry and labour.
Unless you're talking about the farmers who were ruined by NaFTA not going far enough, the idea that the working-class in Mexico were hurt by NAFTA is ridiculous.
You could argue that the working class in Mexico gained some in economic benefits and lost some in quality of life, as the displacement of poorer farmers to the cities caused a surge in unemployment, housing issues, petty crime, organized prostitution, and was a contributor to the flow of illegal immigrants to the U.S., who pay gang-affiliated
coyotes to bring them across the border (thus, financing crime).
Something like 15% - 20% of Mexicos beef products are sold by a group of subsidiaries of an American company based in Virginia(?), and considering how sh_tty America's food products are, that's also a health concern if meat is processed the same there it is here.
The trade debate isn't
just about economics.
