Why There’s So Much Confusion over What “Inflation” Means
Understood properly, inflation is not a general increase in prices but is an increase in the money supply “out of thin air” which brings about the impoverishment of wealth generators.
When inflation is seen as a general increase in prices, then anything that contributes to price increases is called inflationary. In this framework, not only does the central bank have nothing to do with inflation, on the contrary, the bank is regarded as an inflation fighter.

To avoid being blamed for the nefarious consequences of inflation, the government and its henchmen resort to a semantic trick. They try to change the meaning of the terms.

Because of the reduced weight of gold coins that were returned to citizens, the ruler was able to generate extra coins that were employed to pay for his expenses. What was passing as a gold coin of a fixed weight was in fact a lighter gold coin. On this Rothbard wrote,
More characteristically, the mint melted and re – coined all the coins of the realm, giving the subjects back the same number of “pounds” or “marks”, but of a lighter weight. The leftover ounces of gold or silver were pocketed by
