Again you show you don't understand what you criticize. Th market can't "enforce" anything.
Markets encourage some behaviors and discourage others, which may be not always in the best interest for themselves and everybody else in the long-term, because individuals often think and act too short-sightedly. That's all I meant.
Why do you want to "incentivize" women to breed and not leave that up to their own reasoned out choice? Why not incentivize them to be barefoot and in the kitchen while you're about it?
