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.
