Capitalism requires governments to cater mainly to economics, which is possibly the reason U. S. city streets are laid out on grid patterns. Oops there goes public spaces. James Wines:
I lived in Italy for a long time, and the thing I noticed the most in coming back from Europe is that those cities were conceived from the outset with the idea that there will be a public domain. New York evolved as an economic force on a grid and primarily for opportunism. It’s very difficult after the fact to take that paving grid view of the world and loosen it up.
