Living in a city is kinda fucked for Americans who want to settle down and/or have kids. Moving to the 'burbs means:

• You're paying vastly less money for vastly more space. You'd be hard pressed to even find something you could make a down payment for in big metro areas for most people, and if you did manage to snag it you'll be paying $3k+/month for the mortgage instead of <$2k/month
• You have access to far better public schools generally. Public schools inside cities are notoriously fucked by arcane property-taxes-become-school-funds shenanigans designed to fuck over the inner cities by racist white people, and while private schools can be really good they can also cost college tuition-level prices
• Your cost-of-living drops dramatically. Groceries, eating out, entertainment, etc are almost always more expensive in dense urban areas, especially since a lot of those are on islands or otherwise in places where it's more difficult to ship stuff in

The only thing you lose out on is public transit which is absolute dogshit even in most major American cities anyway, so unless you live in Chicago/New York/<insert placeholder here for your city so someone from every city in the US doesn't immediately get big mad in my DMs> this is a no-brainer.

It's fucked and ultimately solvable by a society that actually gives enough of a shit to collectively fix it, but for individuals it's hard to lob blame at people.
