Obviously many commentators do not understand/are  dismissive of the inclusion of gender, climate change and aboriginal issues. However if not included then those issues will be ignored and used as a future lever against trade partners. While Trump whines about Mexico's so called trade advantage, if the previous NAFTA negotiators had put STRONG labor rules into the deal maybe we would not have had major US and Canadian companies going to Mexico to take advantage of cheap labor. Trump can complain all he likes but much of the Mexican trade imbalance is through his own US companies taking advantage of weak labor, environmental provisions. If they had been strong, included in the main part of the treaty, maybe things would be different now. Same with climate change; either we all take action or the one that does not has an advantage. Same with gender and aboriginal issues.
