The concept is really simple -- most people get rich becuase they love what they do for a living. And they are good at it. And, as chance would have it, the things they like to do are in demand by others -- so they also are getting paid well. Many other people have no such luck. They like to do things that others do not find all that valuable. Or they don't possess enough talents to compete with those who do. Those people have to work hard to earn a basic living and the money is the main thing that motivates them to work. That is why the rich are so fortunate. And that is why asking them to pay higher taxes is only fair. Also that is why higher taxes would not discourage them from working -- remember, they are not providing their services just for money! I believe that a society should reward people primary for their efforts -- and much less the end result, as the productivity can change dramatically between the different lines of work. The society should encourage higher productivity as well by allowing some inequality -- by letting people take home many times the average salary. But there is nothing wrong if people making millions would have to give up most of their income in taxes.
