Well, I'm really not interested in barring the kind of people you're talking about from ever getting direct citizenship. I just have not considered all the various implications into the future if you open up these provisions to private business. For individuals who go and live outside, it does benefit the country. There's no question about it. If you're teaching outside, you're a professor, and you come back, or if you're working outside, if you run a company in some other country—all of this has benefits for Canada.
I simply considered a limited area for myself, because it was easier to deal with, and there weren't many philosophical questions about how far to extend the right of citizenship. If you do what you're suggesting, I think you need a larger debate. I may be behind the times, but I don't know whether Canadians are ready to open up these provisions to the possibilities you're talking about.
