If girls are not taught to be wives & mothers, they won’t be. Unfortunately, feminism teaches the exact opposite of that: they tell girls to be strong & independent, equal to men. But except for voting, that’s not true; men and women are not equal. Men have far more testosterone, which gives them different drives, motivations & capabilities than women. In denying those differences exist, modern feminist thought denies reality, no matter how good it may sound in the abstract. What happens is that girls are taught to aspire to be the man they want to marry rather than the wife a man wants to marry.
Evolution has placed the desire to lead & provide into men’s psyche. Similarly, women are born with the desire to serve & nurture. However, it’s not logically obvious that giving childbirth then raising children during the prime of life is extremely fulfilling. Young women who can perform that act don’t yet have the experience to know what they’re missing, and when they finally do, the opportunity has passed. Left to their own devices without the impetus of their forebears and society to form traditional male-female partnerships, society will simply dissolve from lack of procreation.
