The effects you described are absolutely real, but your abuse of control theory jargon deserves condemnation. Positive feedback is when a process reinforces itself: the uglier you are, the more others hate you, the uglier you become. Negative feedback is when a process cancels itself: the better you look, the more others envy and sabotage you, at some point you can't go further.
