The endgame position on #Immigration (if you actually care about maximizing prosperity for ALL people of different cultures) is that it's a net-negative for all countries involved, and the correct amount of it is ZERO.
#Multiculturalism is a scam. #Remigration and ultimately the return to #Nationalism is the most logical way to return to a world where people with opposing lifestyles & beliefs can live in their own nations, without being forced to live next door to clashing ideologies that make them uncomfortable and inevitably lead to violence.
It is that simple.
