Which countries would benefit most from an American brain drain?

Article is built on false premises. Notably citing: "in 2022-24, by our calculations, 20m well-educated people wanted to move there, compared with 14m who preferred Canada (which has a much smaller population). "

Two things: "wanted" and "actively doing so" are worlds apart. Additionally, other countries have about the same or even more complicated immigration rules.

The USA are safe from brain drain. And I'm saying that as a one living in Canada with close friends at McGill University - students still see the USA a primary destination of their interest.

There's a lot of people who threaten they will move to Canada. Far fewer actually follow through

It's almost impossible to get residency in Canada, short of marriage and for most US citizens.

If you are a French speaking PhD in a preferred industry who is under 29 years old, you may be gtg.

>It's almost impossible to get residency in Canada

How does that square with the fact that 1/5 of the Canadian population were born abroad? Seems plenty are able to move there.
