I think you'll find that birthrates are negatively correlated with education level, so globally the reverse is happening (with regards to your breeding theory).

But more generally, the reason why evolution works is because organisms are not equal (mutation and crossover are random). I don't expect that this will stop any time soon.

IIRC, birthrate (in the developing world?) is correlated with female empowerment. Small stuff like when females have educational and economic opportunities, are not utterly dependent on their males counterparts, have basic humans, etc.
