It's not just that, it is that women have the greater bargaining chip in the relationship. They have the womb for creating babies, so they can make more demands. Also, they make the greater investment into kids (at first, at least, over time it can change), which also warrants "compensation".

I'm not sure what they're supposed to be bargaining about in your view. Have you ever been in a long term relationship? Because what you're describing does not sound like a healthy relationship.

Do you have kids? Who got to stay home with the kids? Who got to work only part time when the kids grew older? Who pays the rent? That sort of thing.

And, as always: on average...

If you don't see it, I don't think I can convince you. There is much to learn about how the world turns.

I have kids, yes. We take care of them together. We both work 4 days a week. She pays the mortgage, I pay childcare.

In a healthy relationship, this is stuff you work out together, not through demands and womb-based bargaining chips.
