The US population is 4 per cent of the entire world's, which means that the vast majority of talented humans is born abroad.
If you can snatch them, they will build SpaceX or Google for you. If not, well, they will do so either elsewhere, or not at all. (South Africa does not seem to be a good place to start business, and neither is Russia.)
Can you gain prosperity by employing three mediocre people instead of one talented one? Maybe, but you won't get a new vibrant sector like Silicon Valley this way.
Europe, where I live, is a lot more gung-ho on mediocrity and forced equality, and we seem to be the ones with clearly stagnating living standards, not you.
So you'd be better-off if SpaceX and Google were Chinese companies?
Also, a lot of the wealth from the tech industry does spill over to the larger community. You're strictly better off having it. If the US had just stuck with their 1970s economy on the theory that any new industries wouldn't distribute their benefits equally, it would be vastly smaller, less powerful and less wealthy. Surely that's obvious?
I don't think that human talent is completely homogeneous, there are certainly places where there is more of it than elsewhere.
That said, I think you underestimate many places. For example, Iran is one of the most ancient civilizations out there, and the Persian diaspora in the US is pretty productive, even though the country proper is a retrograde tyranny with very bad economy.
Iran is not very homogenous. Never was. Something very noticeable with the Iranians here in Denmark is that a lot of them think of themselves as well educated upper middle class despite having fairly average brain power. I've met plenty of nice and likeable people who fled from Iran but their talents don't match their self image.
