I think the set of people you are classifying as middle class- applying their own labor to their own capital, which they own free and clear- is a pretty rarified bunch. Practically speaking, the middle class is a myth created by politicians to justify policy that is against working class interests. There are in my view only two classes: working class and capitalist or ruling class.
