You can buy everything you want with the US dollar but given the abyssal debt of the US government, one could think it will also end in tragedy.
Only if the US lost its Political Power. Currently the USD still holds its value because OPEC standardize on using it for the Oil Currency (Petrodollar), and early aggressive lending to the third world country with USD.
When electric cars become mainstream, I expect there will be a turmoil in the USD
Enjoy the run, but sell at the right times because ultimately it will end in some form of tragedy.
