need a car to do anything in the suburbs, really. hot take: this isn't a coincidence
Ironically, if you can afford it, cities are better than suburbs for schools etc. You can have two layers of people in exactly the same place and never have them interact. The richest and poorest schools are just blocks apart.
We can't, that's why we're moving. It's not to get away from "elements", like prior generations. It's simply too expensive to raise a family in the city. Not to mention, if you moved into the city, your family support structure is likely to be back home.
