Like asserting that Mohammed Ali was propped up by holding the #1 spot in the world of boxing.
Whoever has a #1 spot - to him accrues additional fame, prestige, wealth, power.
The rich man is invited to dinner - the poor man isn't.
Regards,
.Yes he was #1, and not propped up as you said. Then Ken Norton broke his jaw, Shavers cracked his skull. The dollar at one time was not propped up but earned #1.
I just don't think the dollar printing can keep going without creating an increasingly false value that will be untenable to holders of the dollar in reserve.
