> But why have dense urban cities in the 2020's? Why can't suburbs actually live up to the urb part? A suburb living up to the urb part is really just a town or a small city. As for why you have suburbs, I think the primary reasons are economic, though there are social (and in some places racial) reasons as well. As it currently stands, ignoring the problem of atmospheric carbonization and climate change, it's cheaper to centralize industry. This issue is quite poignant in the tech industry, where things are extremely centralized, and where many people flock to the handful of cities that have the biggest tech companies.
