Do you think that would solve anything? I don't recall ever seeing a pajeet on a visa causing some sort of D&I-related trouble. It's almost always white Americans at the forefront of this stuff, with occasional black citizen who caught wind of the easy grift to be made by making the whiteys feel uncomfortable about themselves.In some weird way, a citizenship requirement is enough to yoke some teams back towards 90% white.
Come to think of it, I bet a company which did the opposite and only hired non-citizens would end up with far less wokeness than the Silicon Valley average.
