Since everyone loves debating the prestige of each bank, why not debate the prestige of all the affluent suburbs around the country that many of us have either lived in or are working hard towards moving to one day.
When evaluating an area's prestige, I feel like you should consider more than just towns' with the most expensive real estate and median household income. You should also factor in the area's history, location, cost of living, education/prep schools, and household's net worth ("old money").
For shits and giggles I broke em into BBs (powerhouse areas/counties), elite boutiques (affluent town not necessarily in the most prestigious region), MM (prestigious areas in otherwise less prestigious regions/states), and regional boutiques (prestigious town in basically bumblefuck state).
