> Suburbanites want their palace that they can tightly control

Don't rich people do the same in big cities? That has been my experience. They live in enormous apartments or private homes and drive everywhere. The richest have a personal driver and assistant to do all the chores in their life. The difference with all the other people in that big city: They cannot afford to do the same. The suburbs allows the middle class a chance to get that (some) level of control that they can afford.
