Thanks! The Cantillon that discusses about the booms and busts! I got it now. So, USA spends dollars at the expense of rest of the world. This is definitely one big issue which the Russians and Chinese already know, not surprised that they are dedollarizing because they are foes to America. ECB with EURO aimed at the same thing. EURO was invented with the aim to overcome dollar supremacy, but it has now failed! Am I right?
