It is a by definition narcissist worldview to decide "people don't care about anything and they're stupid and I'm the only one who's right" when you could ask yourself "I wonder what else those people are caring about."
A thin veneer of "I am the only one who understands human needs on a profound level, I am the one who eats my vegetables" does not fool anyone, not really. We all feel the contempt radiating off people who cannot compassionately say, "I wonder why."
