This is such a problem. While some believe they are better than others by birth or acquiring monetary status, it's a no-win situation. If the world were to reach Armageddon tomorrow, the lower caste people would probably still care about the uppers and help them. Then they will have to humble themselves. Or, they can be rejected as they rejected the lowers and be left to die. I use this analogy a lot to keep myself from judging others. If class or money becomes useless, what then? It's possible to happen too.
