US dollar value was held by several pillars, among which- pax americana, petro dollar/assets and innovation sector. Pax americana is dismantled by US itself. Petro chemicals are threatened by ren transition and China. Tech sector still ensures having a lead in innovations. Guess what'll happen when/if pax americana will be fully dead, most important economies like EU/China/India will be able to supply own needs with less petrol products since the rest will com from ren and when/if tech AI pops/turns into a fiasco. Nothing lasts forever and US dollar is no exception

Look at a 100 year purchasing power chart of USD, doesn't look very healthy...

Those people were right, it’s just that it will take more time that what they though.

The difference is now the US has a leader that is actively encouraging its downfall.
