Well, the Pew research organization puts everyone who earns above a certain amount in the upper class. It's about 100k. And we know that the rich have got even richer in the last few years, with a thinning of the "middle" earners. There are plenty of articles out there which focus on the erosion of the middle class. As I mentioned, some people (in the UK for example) are invested in the idea of the working class, and draw the class boundaries between working and middle so as to enlarge the working class. Often this is about preserving their own identity rather than assessing the wealth of different social strata. But living in relative comfort has been a middle class thing.
