You're missing the point; the middle class is an invention of the ruling class to divide the working class so we can fight amongst each other about collar-based gentrification and other nonsense.
Maybe my analogy was bad. You are still saying the same thing as me. Im pointing out the illusion of class differences or your "dividing line" when i describe the levels on the turd. Im not saying i see the lines. Im pointing at the trick that people fall for which you clearly agree with.
It used to exist to a degree, but has been erased over the last sixty years or so. Gee, I wonder what was going on back then that resulted in punishment for the people.
