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…
Kids are an expense. Money is tight.The future is bleak.
That's why I only have one kid (and it was unplanned). Every now and then my wife and I discuss having another one but the cons overcome the pros.
There is no non-selfish reason to bring a kid to this god-forsaken world.
