Are mean and rich synonyms? Maybe:
One thing I find interesting in this TED talk is that the research results (the wealthier you perceive yourself to be, the meaner you get) can be reversed with simple reminders that there are people in need, and you can help.
Another thing I find interesting is the list of traits correlated with greater social equality (better health, educational performance, life expectancy, social trust, community life, economic growth, social mobility). In other words, though it’s counter-intuitive, being selfish, and making of selfishness a virtue, doesn’t really pay off in absolute terms–either for society or for individuals. To thrive optimally, you’ve got to have balance in your life (some sensible combination of self interest and altruism).
In any case, this is not a great research discovery for fans of Nietzsche and Ayn Rand.
