Nobody is going to spend that kind of money (4x local students) to go to anything but a world-class institution if they can manage it. I was an international student who had to choose between the U.S. and Canada, my first choice being the U.S. because the school in question was just so much better. But here's where it gets interesting:

Tuition at the U.S. topped out at $40,000 USD/year (it's probably grown since then). Simply unaffordable for my parent's middle-class means and this was after a generous $10,000 USD/year scholarship. Tuition in the Canadian school I attended was approximately $10,000 CAD/year (which was about 1.5-2.0x the local rate then). School was so-so but $10,000 CAD/year was great value after considering the facilities I had access to and the relative quality of the education I received.
