What makes you think other countries with rapid inflation don't manage currency supply? If the monetary base suddenly doubles, the money will trickle down soon enough. In US dollars case, it will trickle down to people and almost all other countries. Those countries will have more dollars in reserve, thus raising value of their currency or giving them low interest rates or ability to print even more. This is extremely evident in the case of emerging markets like China. They will now get even more printed dollars in reserve and the only way to absorb it all is to print more yuan and allow more money to flow through China's economy, thus increasing wealth of the hundreds of millions still in poverty.
