This post seems unnecessarily harsh.

    would require women to choose better mates

Or: Men should pay and do their fair share?

Then:

    How many women are out there with three kids by three different fathers?

Let's turn that around:

    How many men are out there with three kids by three different mothers?

Sadly, a lot. And few of them are pulling their weight in term of parenting and financial support. I'm not talking about the Elon Musks of the world.

    Custody laws typically place all the power in the hands of the mother

Multiple other posters have noted this is highly location dependent. This may have been true in many places around the highly developed world in the 1990s, but no longer.

    most mothers are fine with the father having minimal contact

Ridiculous. Most mothers would like the father to much more involved. Divorce or single parenthood is hard enough.

My post isn't harsh at all. There's a whole world out there that doesn't revolve around middle class nuclear families. I meant every word of what I said, and it's all correct. There are very few mothers who want to share custodial time equally with the fathers of their children because there is an economic incentive for them not to. Most breakups are not amicable and women know that they can punish their former partners in court.

That you don't like it doesn't mean that it isn't reality. In the United States, if the mother wants custody then the mother is getting custody unless there are legal / drug / behavioral issues with the mother that prevent her from doing so. You can just sit around and listen to any radio station for all of the family lawyers who specialize in advocating for men because of how biased the system is.
