I think the ultimate solution is to get to the point where everything is very cheap. With AI and robotics, maybe this will be possible. Then wealth doesn't matter that much - everyone could be relatively much wealthier than they are today. Truly scarce things will only be for the rich. Who cares, let them have their gold and premium real estate.

If most people can live forever, they’ll rebel against the conditions they live in. I suspect the rich would actually perish.

A lot of life now is ordained on the idea that we don’t live forever and we can’t see change in our lifetimes… but if the lifetime is forever - well, I’m gonna fight to make it better immediately cause then I have forever to enjoy it.

Unless we get rid of capitalism as well. Or, at least, force these people to pay taxes that prevent the accumulation of wealth and its undue influence in politics.
