Help me figure out what I mean by "social class"

Help me write my next column figure out what I mean by the phrase "social class"!

--What do people mean when they say "class"?
--What do I mean when I say "class"?
--What should I mean when I say "class"?

I do not necessarily mind that my own and other people's use of the term is vague and inconsistent and contrary, but I do think I should be more specific about the various different species that my inconsistency and contrariness suggest and my vagueness covers up.
