We’ll never have equality until women are more discerning about the men they procreate with, and have discussions around childcare and work impacts before conception.
Unfortunately, for a lot of women the biological urge to procreate is stronger than the requirement to find a decent man, and then they turn to Mumsnet wanting to know why the man won’t pay maintenance and how they should cope all alone. Of course there will be the occasional case of a strong marriage breaking down, but not the vast amount of “how can I get my baby daddy to pay” that we see.
As everyone is aware this is illegal but be perfectly honest - do you blame him? I have read threads on here about women who have been offered a job and didn't know whether to tell them she is pregnant, I know people who have worked for the minimum time before having a year off maternity cover, go back for a few months and then be pregnant again. I also know someone who joined the civil service doing a job way below her level simply because the maternity terms are so good.
Fucking hell. Instead of analysis of the issues facing women in the world of paid work we have some ugly, unvarnished, old fashioned misogyny. Full marks for "baby daddy". 
No mention of workplaces structured with the assumption that the workers have someone at home taking care of children for free.
No mention of how the state lets men who are unscrupulous get away with paying a pittance in child support.
All of that happens because regardless of the well known fact that women bear the babies in any given couple, regardless of the well known fact that babies and children exist, workplaces are structured to suit men who do not have childcare to worry about.
There are economies that buzz along very nicely yet still give generous paid parental leave and provide universal childcare for buttons.
This is because those sensible societies correctly understand that babies are necessary for economic growth in the future, are committed to making equality a reality, and therefore they see childcare is seen as a vital part of the infrastructure.
I blame him because he is part of the problem. He won't write to his MP and complain about the extortionate cost of childcare. He won't complain about unaffordable maternity leave. He won't advocate for true equality for women. He will instead mutter about lack of reliability and if he is as good as his word he will hire employees from half of the available pool.
