I don't think US realizes that Canada and Australia are actively poaching talent. These guys work there for a couple of years, some of them start startups, businesses. They hire other top people (both local and talented immigrants). Then they sell their products/services to the whole world! Major companies get attracted to areas with talent. That's why so so many companies have major offices in India now. Because of the pool of talent. Not just because of cost-cutting. An example is: If Amazon doesn't hire enough smart people, they won't be able to expand/move nimbly and will get beaten by Flipkart in India (who have their own empire desires).
