Anecdata: I am 31 and have 3 young kids. They have 0 cousins and, on top of that, 0... second cousins? Cousins-once-removed? Whatever the one is for my cousin's kids. My kids are my grandma's only great-grandkids. And I have... 6 cousins. On top of that, at my last job, on my team of 15, I was the only one with kids, and only 1 of those 15 engineers were under the age of 30. At my current job, my team is 8, and again…
- social media (want beautiful family to post n get likes)
- online dating want the most attractive I can get so I can get likes for who I'm with and kids i made
- thus everyone is pursuing a certain types/groups who they interact with and get burned by cause they have so much choice ..then get jaded about dating.
Again those reasons are by far not on the top of list reasons why but are on the list.
Maybe Hollywood needs to start reshaping our beauty standards for the sake of the human race ;-)
