College educated couples who got married after the age of 30 are exactly the sort to buy a house before having kids. They’ll also have locked-in friends and family who they can count-on, and likely owe them favors. Other than grandparents and single people, these ARE the society you want in your corner.

As someone who did it in the reverse order, I promise you, you’re gonna burn a friendship or familial relation or three out of need, ones that otherwise would have lasted generations, and know as its happenning you’ll be living with that regret the rest of your life. You may be able to pay them back, but almost certainly neither in-kind or in any way, or on any time-scale, that makes the relationship what it once was.

As you get older, relationships ossify - it takes life-changing events to have any chance to undo extinction events or straight “I’m burned-out on their shit”.

So yeah, I have a lot of people who know that I, and my kids know, our family owes them and I will do anything in my power to do whatever I can to help them should they ever ask. They even would likely still help with whatever I asked for, even non-sense(“we’re square”)…

… BUT, they stopped coming to fun “note-worthy” things we invite them to many years-ago. Any sharing in our modest successes(or just relief that x milestone was reached) is tainted by all the dirty-dirty of all the sausage they’ve helped us make to get to here.
