Inflation increases the cost of goods, the value of the money goes down. I remember hearing, back in the 70’s, that a dollar was worth 26 cents. Your money buys less and less, and the prices continue to increase. At the end of WWII, inflation was so bad in Austria, that they had to print 1 million mark notes and print them so fast that they could only print them on one side. It took a whole grocery bag full of these marks to buy a single loaf of bread.
