Outstanding, thank you for sharing.
Depending on how you define the break, I'm either the last Gen X or the first of the Millennials. I was on track for no kids as well, simply because I never wanted them. I date much younger, and when I met my current girlfriend she insisted she didn't ever want kids. I laughed and said "me too, but I'll bet you'll change that thought sometime in your mid 20s." Now we're planning kids (because as predicted she got baby fever), and most of my day is mentally occupied with thoughts of how to raise them to be hardcore extremists and that is far more fulfilling and exciting than anything else I had rattling around up there for the last decade. I'm being a bit glib and glossing over the full picture (obviously just passing on your genes and shepherding the next generation is a very lovely thought).
Another thing this article alluded to is something I have seen in my own friend group (late 30s - mid 40s men): the complete prevalence of circumcisions and vasectomies. Most of my high school pals had 1-2 kids and then got snipped. That is the second most Jewish thing I have ever heard, right after the circumcision. And all of them are (roughly speaking) white Christians.
What a bizarre concept to let a doctor cut around your junk just because you are too lazy to pull out. And are terrified at having -- gasp -- more than a replacement level of children even though you are in the top 10% earners in the entire earth.
But so many people just do these things unthinkingly.
