This illustrates the real problem with NFTA. As long a there is significantly depressed wages in one of the three signatory partners the employers can create an environment in which the work forces in three countries are in competition against one another while doing the same jobs and working for the same company. Under a truly improved NFTA agreement there should be only one universal wage spanning from Canada to Mexico; one wage, one benefit package, and one collective agreement, and pension plan, along with tax equality, this would mean the same international union representing all workers working for the same corporate entity doing the same work. In addition, this might be a more realistic alternative to building a wall to curb illegal immigration.  Families in Mexico would have access to North American wages  without having to uproot themselves.
