The U.S. attracts the best and the brightest. And if they can't stay here after their educaiton they end up with an ally, like "The Russian Dude" in Canada. The U.S. is never unified on anything. The system is structurally broken. A complete clusterfck. As a Russian on Medium said, no immigrant has ever complained about being here. My experience too. Many ganged up on the U.S. during WWII. They didn't get it then, they don't get it now.
