If there is no ‘price level,’ how could anyone prove that monetary inflation raises prices? According to Wikipedia, “The general price level is a hypothetical measure of overall prices for some set of goods and services, in an economy or monetary union during a given interval, normalized relative to some base set. Typically, the general price level is approximated with a daily price index, normally the Daily CPI.” This says that there is no such thing as a price level. If there was a price level, then everyone would pay the same amount for different things. There is no set price because of inflation, so the prices just keep rising.
