Women have to compete more and more for less and less suitable men
no you've got it wrong, men are remaining un partnered because women are increasingly waking up and seeing that they have very little reason to partner up with a man, they can have better lives if they stay single.
This is it - we don't have to partner up with a man - that situation was artificially created by stopping us from working and writing laws as though men were the real people and we were just property.
The laws are there now - we don't have to have men if we don't want them, so our standards can be higher. Men can either meet these standards, or not - up to them - it's not our problem to solve though, it's the men that need to raise their game.
Of course, yes, it could all go to some apocalypse level of shit, but for now, I'll assume that with a little wriggling back and forth, civilisation will stay much as they have for the last couple of hundred years, and, much as women fought their way out of the kitchen and into the workplace, men worth having will fight just as hard to get out of the workplace and into the kitchen.
