I think, it's way more complicated. Different people could have a very different definition of prosperity. Someone would fine with a dorm bed, while others would strive towards buying that 3-storey mansion they dreamed about since childhood. Earth simply doesn't have enough resources for everyone to have any level of luxury they could imagine, so there has to be some capping mechanism. So far, the deal was doing something that others would find useful, getting others to pay for it and using that money to pursue your own dreams. If we take that mechanism out of equation, we might be opening a much bigger can of worms. If you would accept my analogy with a farm, the crop yield per worker may get higher, but instead of working at the field together because we all want that bread at the end of the day, we will be spending most of our time arguing on who's more entitled to get served first.
