Ok... but this still isn't even within orders of magnitude of 'upper class', is it?
middle class and middle income are often mixed up. upper class and upper income less so.
old text:
well if the definition of middle class ends at 106k income per year then anything above that must be upper class. the problem here is that obviously upper class has a very wide range which skews the perception of what makes upper class.
of course definitions are just that. the reality is not so clear cut.
apparently, middle income and middle class are often used interchangeably even though they don't mean quite the same thing, while arguable upper income and upper class are much more different.
