I came from a household in the top 5% in terms of income. This is about $200,000. For my family, this was both parents working and both making over 6 figures. Both my parents were professionals and had graduate degrees. This was pretty typical for the neighborhood. All my friends, neighbors, and schoolmates came from households of either two professionals, or one super-star professional and a housewife.

In my world no one divorced. I didn't know any kids with divorced parents except one, and he was more of an acquaintance. I didn't know anyone raised by a single parent. The only two families I knew that divorced happened after the kids went to university. Of course my parents fought and I even saw my friends parents fight when I'd be at their houses, but none of the parents divorced.

I also never ran into feminism. We learned about the feminist movements in highschool history class, but I didn't know any feminists in real life. Everyone agreed women should be equals under the law and able to vote, but no one was running around applying feminism to real life.

When I came to university it was the first time I met feminists and kids who had come from broken homes. Even then, it was mostly limited to parties where I would meet randoms, or walking around campus. I went to a prestigious business program and most kids came from a similar background to mine or better, i.e. parents were successful small business owners, executive officers, etc. (which are a level up from professionals).

I'm not a sociologist but the only thing I can draw from this is that the "Decline" that the manosphere and the redpill talks about is limited to the lower and middle-class.
