Billionares are bad since they hoard many more resources than they actually need for a quality life.

Billionares are good since the fact that you can become a billionare can encourage lots of enterpreneurs to innovate and drive the society forward. For example, cars revolutionized transport for all of us, but they probably wouldn't exist if rich people didn't exist.

Well yes, financial incentives for sure drive innovation forward, but nobody needs to be a Billionare to life the best quality life ever. There is literally 0 need for that. The only benefit of being a billionare is being able to accumulate even so much more wealth much faster (e.g. potentially 1000x more wealth than a millionare). So once you are a billionare you are not likely to be financially motivated to grow, but more power-hungry (world business domination, political influence,...), which doesn't bring much positives to the society as a whole.

Well does that matter if they can do potentially much more useful stuff (e.g. create the next groundbreaking innovation) than any single (poorer) person would if that wealth was redistributed for example.
