99% of fertility collapse is due to female “liberation”; collapse of social norms which historically kept feral female sexuality in check. Most morality developed with a proximate or a root cause of keeping female sexuality in check. The loss of these norms is leading to the natural female hypergamous preferences revealing themselves, whereby going single is preferred by most women, over breeding with bottom 90% of men. Eventually Chad sperm banks will replace 90% of men, with state/AI provisioning material resources to women (instead of male partners). Lots of 30yr+ single women who can’t “true love” (aka Chad) these days. Since most women expire at 35, a painful reality awaits single older women. As their sexual power wanes away, they still want to stay relevant, so these women tend to become feminists and/or start participating in some political cause. But there is no free Darwinian lunch in this world; the pain most women inflict in their youthful days on most men, will be reciprocated. The world will make older single woman feel like a useless piece of meat. They will want attention, but no one will give it to them. There is Pattaya for old single men, but a dark gloomy reality faces old single women, a Parveen Babi in the making.
