One thing that I didn't see mentioned in this thread (I read pretty much all of it), is that part of this equation is to provide as much happiness to your society as possible. All this talk of wealth here and there sometimes seems to forget about what's the point of all of this. If you were to set up a society from scratch, wouldn't the goal to be to create conditions that improves the lives of as many citizens as possible. So, wealth creation is important, but if all of that wealth is used in the service of a limited number of the citizens, what's the point?
I live in a country (the Netherlands) that doesn't get everything right by any means. However, we seem to have found a way to allow most of the people, even on the lower end of the socioeconomic scale to live comfortably (enough income, reasonable housing, personal safety, etc.). It sounds, from a distance, that a large number of US citizen do not benefit from the great wealth of the country. The lack of caring for the happiness/comfort/safety for other people in your society (city, state, country, etc.) feels like a lacking to me. I don't want to punish the super wealthy. I want them to care about how to improve the lives of others. If they (or anybody else) have that ability, why wouldn't they want to help?
