> Typically in the scale of millions per year. Which is nothing to walmart guy. Building a modern subway network with a couple dozen stations will cost a few billion easily. And that is just one small thing on a long list. I think you underestimate what infrastructure for a city of millions would cost. Maybe you think cars are ok, but they really are not, if you want a great city. > I dont understand what you mean here. I suspect you're referencing Detroit as a key point. No, What I mean is that most US cities, especially those with large suburbs, cannot cover their existing maintenance costs unless they grow, this will stop working in the near future, see: https://www.strongtowns.org/journal/2020/5/14/americas-growth-ponzi-scheme-md2020 https://www.strongtowns.org/journal/2020/5/14/americas-growt... > this is north america in a nutshell. Virtually everywhere you go there is examples of success... I would argue that most US cities rank low in quality of life comparisons when compared to cities in other developed parts of the world. When planning utopia, I would start looking in other places.
