I can never give a short answer, so I'll do my best.
The comment that you made about the cost factor is very interesting and important to explore. I guess I would pose this back. Part of our expanded thinking about trade and why labour conditions, labour standards, and other social conditions are important is that, if free trade agreements have facilitated the model of globalization that we know, and it facilitated these trade rules around the world, in the case of Mexico, for instance, you could argue that in a lot of ways it was those provisions, the lack of ambition on those issues, that have sort of suppressed Mexicans from enjoying the benefits of expanded trade and seeing the results of expanded productivity. I think if we could explore this in a way where, if social conditions of trade become higher on the priority, there's less of an imbalance in terms of the cost variables between these developing countries and Canada.
Anyway, this is just some food for thought.
