Today, I learned that one of Canada's exports is actually education.
It sounds weird, but I learned this from Economics Explained, and I think I can follow the logic.
A foreign student who studies in Canada brings money into the country. Four years later (or longer), Canada sends that student back to their home country. Canada's economy gets money up-front, while the foreign country gets a smarter student later on.
Economists have a very different way of looking at the world.
