From my article:
Inflation erodes the purchasing power of our hard-earned cash, leaving us with less value over time. Dollar, the most important currency, the reserve currency of the world, inflates when US print more money.
It all resumes to this, think of USA, they pay bills in the order of billions from thin air, basically the federal reserves print money whenever they want, what grows up inflation, and we pay all that back in taxes, maintaining the cycle.
