> now the city has a bunch of more soulless condos and is horribly congested

The first bit is a taste thing; obviously lots of people view modern sprawl as "soulless" too.

But the latter point is just plain wrong. Dense housing IMPROVES traffic congestion and shortens commutes, always, everywhere, markedly. And it's for a bleedingly obvious reason: pack people in closer together and they don't have to travel as far to get where they're going. QED.

What you're imagining is some kind of fantasy hometown, which never increased in population and whose economy never developed. I mean, it's true. Forgotten ghost towns have very little traffic and quirky soulful architecture, c.f. Detroit. Everyone agrees that's a bad thing, though.
