The USA — and, to a much worse degree, Western Europe and Japan — have low birth rates, below replacement level. Poorer countries in Latin America, Africa, and the Middle East also have dropping birth rates; but their birth rates have only just started to drop, while ours have been falling for decades. So we are, or soon shall be, running out of people; they have people to spare. The easy and obvious answer, if we want to keep our populations stable, is to let people from those poorer, more philoprogenitive countries, come and live in ours. Hence the mass immigration that has been a feature of the advanced world — except for Japan — this past few decades. The trouble is, these policies are premised on the Multicultural Theorem; i.e. that masses of people of different races, from different places, practicing different folkways and religions, carrying various kinds of intercultural and interracial grievances, can live together in one country in reasonable harmony. Unfortunately no-one has bothered to prove the Multicultural Theorem; and the evidence is mounting that it may actually turn out to be false.
