In all those years you should have learned that trade has nothing to do with illegal immigration. You should have also learned that the vast majority of people in favor of free(r) markets are also in favor of strict enforcement of our immigration laws.
Since you seem to be focused on NAFTA maybe you can show us how NAFTA caused jobs to go to China. Mexico benefited a great deal from NAFTA. Unfortunately, they chose to maintain their statist economy instead of adopting reforms like they should have. Maybe you can show us how illegal immigration wouldn't be so bad today if NAFTA hadn't passed.
Just as an aside, I think my children will undoubtedly benefit if the unions are ever shut down. I believe they'd thank my generation for helping that along should it ever come to pass.
These two issues do get linked a lot on these threads. The idea is that import tax-cuts caused a "giant sucking sound" of American jobs going to Mexico, which is why we now have unemployed Mexicans trying to fill employment vacancies in the States.
OK, I know it's loopy, but this is how the two issues have been linked.
