Nonsense. There are very walkable and affordable cities with pleasant neighborhoods that don't break the bank in all parts of the world (sans North America). Off the top of my head and from first hand experience: - Warsaw - Glasgow - Porto - Lisbon - Athens (Greece) - Berlin - Budapest - Barcelona (OK, this one gets pricey but is superbly laid out)
To be fair at least some of these cities aren't described as affordable by locals. Berliners are constantly complaining about the rent prices.
Numbeo cost of living index has it 153rd in the world including rent and it's well below places like Houston which is probably the cheapest large top tier city in the US.
