sadest part is how it's impossible to quantify future success in this way. nazi germany just changed with a new leader and became very succesful overnight. china went from 0 to 100 very quickly.  i think a country that just imports the most exceptional people or rather "exceptional" people. will lose out to nations like china where people are more patriotic and feel a sense of belonging wanting their people and country to succeed. america will become a nepotistic battleground and collapse eventually i'm pretty certain of it no matter how many exceptional individuals they import because the societal cohesion will have a overall worse effect than those smart imported people.
