Its all well and good to talk about worldwide standards but the fact of the matter is this: Where would the money come from? Would those individuals who "had" to give it up really want to give it up? Would there be a fight?
I see that as a misunderstanding.
Money isn't a thing. Rather, it's a token that we use to manage the exchange of goods. If productivity increases, there can be more goods for everyone. Nobody has to give up anything.
