Its just mindless burb-bashing, doesn't mean a thing. I can assure you that a school campus in a big city isn't all that different than a school campus in a small city. Ditto museums, bars, concerts, whatever. They'll be some cultural offset what with the people being richer and the surroundings being somewhat more civilized, but its usually not a big deal.

The huge hang up is getting confused about geography. In a big city, nearly every street corner has a bar, restaurant, "something". So you get a hangup that what makes a city friendly somehow has something to do with street intersections or panhandlers or something, not the bar/museum/whatever found at those intersections. Then you visit a suburb and decide to socialize so you've learned that means finding a street intersection, so you stand at a random corner in your subdivision and ... nothing happens. That's because you need to go to a bar or park or cultural activity, not the mere street intersection.

Its confusing correlation with causation. I had fun; there's a homeless dude living in the alley; therefore you can't have fun without a homeless dude in the alley. Um no not really.
