Michael, I would side with you completely if men and women shared custody 50-50 in all cases, and if men and women earned the same money in both situations, and were therefore able to equally financially support their mutual children.
We know that isn't the case. (https://www.pewresearch.org/fact-tank/2021/05/25/gender-pay-gap-facts/#:~:text=The%20gender%20gap%20in%20pay,%2D%20and%20part%2Dtime%20workers.)
I absolutely think (agree with you) that a deeper evaluation ought to be done to determine the best living arrangement for children, that perhaps children ought to be able to advocate more for themselves, but I'm a writer and not a social worker.
I'm glad you had a great father, and you are probably a great father yourself. And indeed there are better ways to align the dollars, no doubt. You'd make a great advocate.
