I think trying to define class by income isn't possible. It should be defined by quality of life I think. That allows for relative lower middle and upper classes. Being a land owner and employer in a tiny town makes you relative upper class even if you're making 75k a year. While as someone else pointed out 127k a year in NYC qualifies you for rent-stabilized apartments, obviously not upper class.
