I know a few people with very high IQs (3-sigma and above) who have been poor and miserable most of their lives, and they are among the most compassionate and sympathetic people I know. If anything, their ethics and compassion have improved during their fight for survival. OTOH, I have met quite a few wealthy people who couldn't care less about the suffering around them. But it's an interesting question: what creates compassion and empathy? Wealth? Suffering? High IQ? Combinations of the above? Which ones?
