because the American companies pay better and even if people managed to come up with something very innovative, they would then be purchased by a US mega corporation anyway. All you will end up with is more or less rich, and frankly the risk is that you go broke. So, why not take the money and work at a US tech company? They’ll get the tech anyway if its good and you get more stability this way.
