I agree there have been a lot of very sad threads recently where the woman has been completely screwed over.
I think there is a discrepancy in society though, we tell kids that men and women need to get jobs to be financially independent, and relationships should be equal so both contributing to bills etc. I think most couples now believe this is the best model for a relationship. Which is all completely fair. Until kids come along.
This model does not work when kids are involved, unless both parties sacrifice their earning potential to the same extent (both pay proportionately for childcare, both try and reduce their hours at work or change jobs to more flexible roles etc).
Covid and home schooling etc showed that the majority of people believe that women should still be responsible for childcare. But it's not possible for women to take on their partners share of childcare as well as their own, while still contributing as much proportionately as they did pre-kids.
Women put up with it though as no one advised them to have these discussions pre children, they don't want to be labelled a money grabbing gold digger, and so many men (and women going by these threads) think this is the natural order of things and shouldn't be challenged.
So although I agree, I think it needs to be part of a wider discussion about what a partnership is, different ways of contributing, and the hidden costs of having children and how that should be shared.
I also think if you're going to get married you need to sign something to say you've discussed things like will you have kids and how finances should be shared (although that doesnt help those that choose not to)
