If the rich are not consuming in proportion to what they have, then what do they do with their money? Right, they invest it. And what does that investment create? Jobs, factories, lower costs, and new opportunities for all. The fact that someone was able to accumulate wealth shows that they know how to use it to generate a return. For the economy in general, it is much more beneficial to have people with skin in the game to invest their own money, instead of the government wasting it in bureaucracy.
