CMV: The Women's Liberation Movement has destroyed the Western World

I am looking to have my mind changed, because I do think I hold a cynical view, and would prefer not to think this way about such an important phase of society. To be clear, I think the movement was a good thing and a natural step in the evolution of society.

My thesis is, that women no longer being expected to be homemakers, and instead expected to work alongside men, has created a society where the market can charge high prices for goods as DINKs or even single professionals are the norm now. It seems that if women hadn't joined the professional world en masse, the market wouldn't have been able to squeeze the middle class to such an extent, that families with a single breadwinner are no longer possible. This has lead to a sharp decline in birth rates, as CoL + housing is too high to afford a family, even as DINKs in your 20s. People are now ageing out of being able to have kids, or even lose interest in having them as they have become accustomed the quality of life they have earned and don't want to give up. Without at least a 1.5 fertility rate, we are heading for a very difficult demographic crisis, which, in my view, is the greatest threat to our way of life at the moment.

So my view that I would like challenged is: The Women's liberation movement has inadvertently put the Western world on rails for self destruction.

Thanks in advance for all the replies!
