Do you think that you would keep your integrity and use your money for the greater good, or that you would be corrupted by your power?
I suppose it's a matter of perspective. Very few people in the world ever see themselves as actually evil. Every villain is the hero in their own story.
But if we recognize basic truths about people's preferences, I think a greater good can be achieved. Everyone wants a place to call home and good food on the table. Everyone wants good health and to have a sense of purpose or meaning to their lives.
This is universal, regardless of race, sex, gender, nationality, language (I can't include religion as some religions demand the oppression & extermination of others).
