> Used to be that America was great because the smartest researchers in the world wanted to come here, often escaping oppressive regimes to do so, and become American citizens (e.g., Albert Einstein)

By this measure, America is now greater than ever.

Of course, it's convenient to pretend that Trump is building a racist dictatorship with a Gestapo, and that's why no one wants to move to the US. But the true is that the number of people around the world who would like to move to the US is higher than ever. Especially when the current administration is trying to purge society of foreign criminals.

> So now all the world’s best and brightest scientists will move to China

Yes, of course. It's practically the same thing. The only reason scientists go to China is because they are not allowed into the US.
