Why does higher literacy rates correspond to lower birth rates?

Question

I understand that the more educated people are more aware of the responsibilities and risks of having children and they use protection more etc. but why is it ALWAYS that more literate and rich populations have lower birth rates? At one point, shouldn’t the literate and able people have children to contribute to the future of their countries?
