I do understand your point! But the population in Africa will grow from 1.4 billion today to more than 4 billion in 2100. Almost a third of all African migrants live in Europe already. We’re not able to absorb many more from Africa/MiddleEast/Asia, financially nor culturally.
Agreed, but even countries that have very few immigrants, like Korea and Japan, are experiencing population collapse. If the birth rate stays as low as it is, the Dutch nation will die out by its own hand.
