I read somewhere that ALL fiat becomes worthless in time. Who is going to change that constant?
There are many chances that the future governments, after dollar, do not use a fiat currency. Actually, there are many chances of having a gold backed reserve currency. You cannot buy oil to another nation with a fiat currency. What we do not know yet is "its color" and the transition process.
In my blissful mind there is not enough gold and oil to fuel the future of mankind. The proof is in the mechanism of transition and power. War!
If there was money to be made in peace then humanity would have equilibrium of wealth. Save for those who would rise up against peace...for their own gain.
The greatest riches that humanity possess is intelligence. Eventually history will stop repeating itself and progress will be governed with
that evolved intelligence toward a more equal stake for all. Minimized by another constant; that some things are more equal than others. There will always be those who fate favors best when it comes to brains, talent or entertainment value. We all have to take time to find that which makes us think, smile and laugh.
Again...IMHO
