Hmmm...very interesting.
It kind of looks like the US students get a little screwed over, though...because the schools knows they'll be able to get loans, I mean. I think this is also the reason behind the crazy inflation of tuition at many US undergrad and graduate/professional schools in recent years, as well. With the ready availability of student loans in very high amounts, there isn't much incentive for schools to control costs, since students will be able to pay.
There was a very interesting program segment on a major US TV network nightly news a couple weeks ago about US citizens going to Canada to study. They interviewed an 18yo young lady from the northeast US who had gotten accepted into Georgetown and McGill, but decided to attend McGill because it is a good school and a ton cheaper (at least 10-15k less tuition/year I think). The reporter also mentioned more and more US students applying to other good Canadian universities (Dalhousie, etc.). I actually think it's a great idea,but I wonder if Canadian universities are going to get flooded with applications from US high school seniors if college tuitions in the US keep going up. I mean, there are so many of us (people in the US) relative to the Canadian population. I'd think at some point the Canadian taxpayers might get kind of irked by subsidizing US students' education and I wonder whether the schools strictly limit the number of foreign students they take.
