I've been talking with my friend about that today. Image what would happen if whole world use 1 currency., or few of them. What would be their price? That's actually imagination and changeable value. Money is a pyramid and the richest will have more and more, but "these down" less and less.
Only if you play their game. If everyone in the bottom of the pyramid wanted play a different game and create their own tokens of value backed by belief and value they created for each other, how could they be stopped? If the rich provide more value, the rich will gain more.
You're right and that's why are we here I guess.
