The middle class doesn't position itself against the poor, the poor position themselves against the rich and the middle class.
Discussion
The poor don’t position themselves at all. That’s the nature of poverty: little voice, little movement, little power, little upward mobility.
That is completely untrue, all communist, socialist, and otherwise totalitarian regeimes were established by poor people used as pawns. You should read history. Middle class cannot claim to be oppressed as long as the mainstream media convinces them they are not. Poor people can be convinced they are oppressed even if you give them free food via welfare and cheap available housing.
