NAFTA hurt Mexicans more than any wall could. NAFTA and the previous application of neoliberal policies starting in the 1980s ended income growth and poverty reduction in Mexico.

NAFTA has harmed workers in the US, too.

Calling NAFTA a "trade treaty" leads people to erroneously suppose that it is a compromise between conflicting interests of various countries — that each decision in NAFTA would pit the interests of Mexicans against the interests of Americans and the interests of Canadians.

In fact, NAFTA is a business-supremacy treaty, and it pit the interest of plutocrats in Canada, Mexico and the US against the interests of most people in Canada, Mexico and the US. That's why we need to get rid of it.
