It is sad but true that those least able to raise a child are having the most children. Africa is way past saturation point whence mass poverty and starvation.

In the West a German author was vilified for arguing that the smartest in our own societies have the least children and that the least intelligent have far more. He also observed the fastest growing group were Muslims. He predicted catastrophe for Europe and 47% of Germans agreed with him despite the media shaming tactics.

A country does NOT need more people. If GDP per head is falling then open borders is not working. It has actually made the West poorer and Africa remains poor because it does not change its attitudes or culture. That is on them to fix and the kindest thing we can do is offer the pill and sex robots. They could keep having 6 kids per woman but that is not smart and is destroying the environment.
