this "development" is easy to explain. women can make money on their own now. women like to have orgasms. BEfore the 70s when women could not make a good living in the workplace, their income depended on men. if a woman can choose to enjoy sex without it affecting her income, she will. who wouldn't?
if you're looking to change this, it isn't gonna happen in church pews. you have to eliminate women's opportunities in the workplace. Not saying that's a good solution, but it's the only realistic one. it's a different world.
A job is a poor substitute for a family.
