I would also add:
I am over 60. I came of age in the early 70’s.
I lived in Calif at the time, all the way up till 40.
I remember the 1970’s at least out in Calif, there was the “overpopulation scare”.
Besides the fight for the “right” to abortion, with abortion being “married” to womens rights,
All we heard out there, from ZPG ect, was to “Stop at Two.” One was better, and none at all was good.
This was the 70’s and 80’s. Kids were seen as someone above pointed out, noisy, messy, expensive, and conflicting with careers. it was socially acceptable to have two-maybe three if the first two were the same sex. More than 3 and people started asking if you knew what caused that, lol.
This is in the U.S. It’s a bit different here in the Midwest(USA), as some families a generation younger than me are having 3-5 kids, but most of these are Christians. Most in my age group did stop at two(or three).
