I don't believe that the "power of women" can be the cause of low birth rate.The women just feel who is the power. As I wrote before, the Left tries to make the minorities a kind of ruling elite, just to get their votes. Also I think last time, that the birth rate in a society is a good indicator of the happieness in this society. Elon Musk would probably agree that impregnating women is a very efficient way to become happier.
If men would grow up and actually talked about parenting and being responsible, doing their emotional work rather then seeing "impregnating women" as a goal, then maybe they would find someone to love them without paying them.
But considering how you and many other men see Elon as a role model in this, i don't hold my breath. Btw i've never seen a family in a cybertruck. That seems to be only for sad and lonely men.
