Most people would like to be richer, more powerful, and more admired, and it may be that their morality is keeping them from that. But most people would probably also like to be more moral, more compassionate, and contribute more to society, and their desire for material success is keeping them from that.

I agree with your larger point, but I have a minor quibble. I don't think 'contribution to society' should be grouped with the second set of goals - generally it's much easier and more productive to contribute through money and power.
