isolationism and nationalism IS america....
selecting for highly intelligent immigrants is eugenicism, one step above racism - since racism at least allows for prejudicial morality, biological determinism doesn't have space for free will, let alone natural genetic variability or universal morality. rich european nations engage in various varian disasters in order to push through more regulations. america engages in predatory forced immigration by destabilizing ripe nations and then preying on their elites with faustian bargains. it's colonialism of the mind.
if world power cared about the poor of africa they would stabilize it with a permanent global peace keeping force for one or two generations, and allow people the freedom and space to develop outside of the debt structure which has crippled them since independence. yes, they would do this by forced occupation, at the gasp cost of national sovereignty. china is engaged and accelerating in this process for the coming decades, and in return will secure resources for the next century of cold war.
assad said something very telling when asked before the 2016 us presidential election who he preferred, it was something to the effect of "we don't listen to what the american politicians say, because they always do the opposite when they come to power. we will wait to see what they do."
it's unfortunate that so many people just accept what america says, and avoid looking at what it does, has done, will do.
