I see your point. Well, thats the incentive. The more I work, the more money I make, and the more nice things I can have. And I don't see rich people as uber mega evil corporations out to get us all, I mean, if every one of the companies run by "rich" people were to go out of business, a lot of jobs would be lost.
I agree with you, in my opinion, I wouldn't want to idealize making tons of money either. You don't have to be an uber rich person to be happy, you know. If I ever did become an uber rich person, however, I would (as I encourage most people with more money than they need) to give it back. An example would be some of the super rich christian groups, like KCM, who are super rich, but give back more than 90% of said money to other through free merchandise, sure it isn't straight money, usually, but they are using the money people give to them to do stuff like giving out free DVDs on their teachings, building a college with free boarding, stuff like that.
And thats just the minority of christians. Can you imagine if every rich person gave like, 50% of their money back to people, through things like charity? wouldn't that be nice.
