You hit a key point, which is that it's not so dissimilar in other sectors. The United States has the Jones Act that protects their shipping industry. They have a series of measures to protect their busing industry, as far as content, manufacturing, and assembly. They have a series of farm subsidies that are very unique; a series of border protection elements that are critical for food safety; and a series of other types of measures for their manufacturing society.
So I think it's important that when we look at the cultural element here, we don't forget that this is not only just a major industry, as well, and that we may claim, on this side, to go to this free market economy that seems to be exposed out there, but the reality is that our neighbour doesn't prescribe to that itself.
