Another way of thinking about it is the human potential it would open up and create.

Imagine limiting the wealth of the those with enormous fortunes and allowing those in the middle to become enormously wealthy, while at the same time allow those at the bottom to finally make it to a level where they no longer have to worry about surviving. It would be terrible for those with enormous wealth because they would lose control but it would great for those at the bottom who would achieve a way to take back control of their lives.

Imagine a world where those who never had the opportunity now have a chance to become doctors, engineers, scientists, professionals, creators, builders and inventors. Imagine a world filled with people who have the free time to just create things because they can instead of spending their lives just trying to get by. Most people in the world don't want to become master and ruler of the universe ... they just want to have a nice life, do something useful and enjoy their existence with others. It's only a minority few who feel compelled to neurotically want to collect every bit of wealth everywhere and pathologically amass so much wealth, it would take a thousand lifetimes to actually use it, let alone enjoy it.

Imagine every poor inner city kid build up an education to become a professional at something and not worry about how they are going to make a living. Imagine a millions of poor kids in Indian and China doing something with their time in engineering, science or medicine. Imagine every poor kid in Africa building their countries and developing new ideas.

The world wouldn't become a utopia ... it would most likely still have all the problems we deal with today ... but at the very least, we would have a world full of educated, capable people who would be able to handle it all. Right now, we're just a horde of raging mindless apes that are worried about dying and will kill one another for a share of a few bananas.
