"Inflation is always and everywhere a monetary phenomenon" - Dr. Milton Friedman
Inflation has causes on both the demand side and the supply side of the economy. Monetary policy affects the demand side, and hyperinflation can result from very loose monetary policy and heavy money-printing. Lack of supply, resulting from oligopolies, lack of competition, and high tax rates, also causes inflation.
Unavoidable inflation is baked into the Private Central Bank (”Federal” Reserve) fiat currency policy.
The Fed always skims value, giving us paper money to use, but always with interest to be paid—one way or another—leading to the borrowers’ loss of value.
