The truth is that those white scientists/inventors only constitute a fraction of the entire white American population, and they cannot sustain the entire American hegemony.
Most white Americans are either freeloaders or high school dropouts who can barely solve any basic arithmetic operation.
The elite groups of America are still made up by the white Americans, but they desperately need those non-white talents to do the high tech jobs.
Obama is in fact a token black guy who worked for his white masters, and his plan to spread chaos across Europe and Russia could in fact bring more white immigrants with high educational background to America, but unfortunately now America is getting stuck with an outside guy like Trump who doesn't have a clue about the world geopolitical game.
He doesn't want to keep enacting Obama's plan to destabilize Europe and Russia, so no more educated white immigrants from Europe and Russia would come to America.
He keep discriminating against those non-white immigrants who is now sustaining the majority of the high tech jobs in the US.
As the biggest peer competitor of the US, there can be more gleeful for China to see the US has now triggered its self-destructive mode.
Some of them are either extremely native and got brainwashed by the western propaganda, and some of them are just self-hatred losers with no self-esteem and prestige.
That's why the Asian Americans who voted Trump now generally have a very bad reputation among their community.
