As a sibling comment has mentioned, there are high-skills immigration paths in the US, they just aren't very well known, and have a very high bar to clear. It's not great, but it does exist. I personally know 2 Indians who got their green card in a matter of months.

That said, the Canadian system, while definitely better than the US system, still isn't that great, and not something to model after. Specifically, it gives too much weight to credentialing, which is unfair in its own right, and still very much subject to gaming.

I personally believe in complete free movement of labor (which totally existed before, the current state of things is relatively young), but that seems politically infeasible around the world right now. Brexit is an example of even taking a step back from it. Maybe this will someday happen in my lifetime.
