The Schengen zone has been very efficient at preventing Africans from getting in and staying there. The result is that they can only go by sea, and many die there.

I agree that the correct solution for this problem is for the powerful countries to stop messing up Africa to enrich the rich. However, Africans must play their part by reducing their population growth and stabilizing their population. (Every part of Earth must stabilize its population, then reduce it to a sustainable level by the one humane method — fewer births.)
