I'm wondering if it comes with the size of the city. Everyone wanting to live in the same place at once is a logistical nightmare that won't be solved in our lifetime. One can compromise; a medium sized city with rapid growth offers high pay, low cost lifestyles that don't rely on genius politicians to have the answers. Such a city simply faces smaller, more solvable problems. Parking is free everywhere in at least one such city of 1M. And several others I've lived in or visited.
