it might be enough to make a 22 yr old in Mississippi upper class, but in no sense of the word is 100k upper class. Especially if you've got a family. I'd say upper class starts where you have enough money to live off the interest. Drs, lawyers, etc are upper middle. And industrial wage earners and most fresh college grads are lower middle. 100-200k earners would be middle middle. Aristocracy isn't really much of a thing. Yeah, there's plenty of "old money", but that falls into the upper class category. As stated in another comment, in the US, it's really the size of you bank account, not your name, or your accent, or where your from, or what school you went to, or what "estate" you live in that matters.
