Forgot to mention pets, which are much the yuppy substituted for kids, not as a supplement to them. .
they really resent their female coworkers with children and grandchildren; the two groups drift apart, and oddly enough it seems those with families work harder (probably because they need the job more).
I live in a populous small city of mostly working Latinos, and who almost always have kids. Well, the newer city leaders let two large old factory buildings get rehabbed in the neighborhood we used to live in, and turned into condos. It got filled it up with yuppies, and the contrast was stark.
I saw zero children from there in the years we were in that neighborhood even though there was a park right next store. And zero interaction with the neighborhood (and with whom I had much interaction, by the grace of God, despite the language barrier) But pets! This is what they had, and the only yard was a lawn in back that was used for the dogs. Great fertilizer.
In my town here in NJ (once Scots and Irish, now primarily Hispanic) we got our first “bark park” a couple of years ago; now the ageing childless Americans take their dogs there while a mile south the young foreigners fill the athletic fields.
