It is all relative to value of dollar on ways ok.
That is the issue we are going though an interesting revaluation this could see it go this high in current value of the dollar but I think the dollar will eventually be stronger and more backed by things this may trim it to 150 or so but I think it will remain high. This will also retain the buying power the same at 150 and 600 being the same in value when it is reevaluated so on. This is very rude estimation. The 150 would be healthier for the global economy as well for the US if it is 600 the world is fucked and the US not in the best shape but would service believe it or not.
