You're romanticizing something real, but you're also being kind of unfair to people making different choices. Yes, suburbs can be isolating. I grew up in one and felt that acutely. But I also grew up safe - not because of segregation but because my parents could actually afford a home with space, and their money went toward that instead of being extracted as rent every month. That's not nothing, especially if you're working class or have experienced housing instability.
I live in a city now too, and I love it. But my suburban friends aren't all driving to the grocery store in a stupor. Some of them have massive community gardens, their kids go to diverse schools, they host block parties. Meanwhile, I'm paying 40% of my income for a smaller space and watching gentrification displace families who've lived here for decades. The neighborhood you're describing - that sounds pretty gentrified, honestly. How much are you paying for the privilege of walking to those restaurants and museums? Because someone's probably been pushed out so you could have it.
Both choices have real costs. Both have real benefits. The thing that bothers me about your post is that it assumes suburban people are duped, that they're buying some false bill of goods. But a lot of them made a conscious trade-off that works for their family. That's not moral failure. That's just different priorities.
