Good food is what we need, however the issue is trade imbalance and of course that wall no one wants to pay for. Nafta was supposed to regard these imbalances and has a remedy for those imbalances.

The root of the problem is the USA likes good inexpensive products. When this stared in Bush 1 and signed into law by Clinton, people in the USA complained but no one listened. What is the difference from the 1990's and today?
