How laughable, irresponsible and absurd.
“We are thoughtful, they are barbarians, hence the looming collapse”
It’s narrow minded bigotry.
Though among those with ‘lots of education’ you find Hillary voters — Trump voters have, on average slightly more education and income than Clinton voters. Does that make those ‘single degree holders’ the harbringers of collapse.
As far as diverse population — you’re essentially saying that America should not have brought them here.
