     It is matter of common observation that although money incomes keep going up over years, we

never seem to become much better off! Prices are rising continuously. This condition is named one

of inflation(通货膨胀);the money supply is becoming inflated so that each unit of it becomes less

valuable. We have grown used in recent years to higher and higher rates of inflation. What could

be bought ten years ago for one dollar now costs well over two dollars. Present indications (迹象)

are that this rate of inflation is tending to rise rather than to fall. If in the real word our money incomes

go up at the same rate as prices, one might think that inflation does not matter. But it does. When

money is losing value it lacks one of the qualities of a good money-stability(坚固性)of value. It is

no longer acceptable as a store of value; and it becomes unsuitable standard of deferred(延期的)

payments. Nobody wants to hold a wasting asset (财产),so people try to get rid of money as quickly

as possible. Inflation therefore stimulates (刺激) consumer spending, and prevents saving.
