The NAFTA argument is a nonstarter. While American yellow corn is subsidized and thus cheaper than Mexican what happened was more complex.

Mexican industrial farmers had been producing yelow corn for animal feed and switched over to white corn used for food. The industrialists came to dominate the supply of white corn to the idustrial market previously supplied by rural farmers. The Mexican village production would have been able to find markets.

The failure was that added value should have been added in the villages locally. There is a rising demand for meat and as much corn as the villages could produce could have been used between locally processed food and feed. Instead it was too easy to go north. This meant that it became increasingly hard to staff a traditional farm. Young risk takers who could have made a career in meat left to work illegally in the U.S.
