"In inflation, everything gets more valuable except money"

A good definition of INFLATION from YourDictionary.com:

We define inflation as an increase in the amount of money and credit in relation to the supply of goods and services. Often, inflation is erroneously defined by the effect that it has on the economy. When people notice that gas, food, and lodging is getting more expensive, they often label that phenomenon inflation. Rising prices, however, are really just the result of inflation.

When money enters circulation at a rate that is higher than the supply of goods available, inflation is occurring. There is typically a correlation between the quantity of goods available and the amount of money in circulation. If more goods become available, more money must be put into circulation or prices will actually drop.

In theory, the free enterprise system operates on the basis of competition. Those who produce the highest goods at the most affordable prices succeed. If a company was artificially inflating its prices, theoretically, its customers would eventually take their business elsewhere. However, when seeking to define inflation, the dollar itself is worth less because the supply of dollars has increased. Businesses must then raise prices to recover their losses in an attempt to get the same value for their goods and services.
