Suppose you are driving on a highway with three lanes going in your direction and you come upon a toll plaza with six toll booths.Three toll booths are straight ahead in the three lanes of traffic,and the three other booths are off to the right.Which lane should you choose?(86) There are usually enough people searching for the shortest line so as to make all the lines about the same length.
The term profit in economics has a very precise meaning.Economists,however,often loosely refer to “good deals” or profitable ventures with no risk as profit opportunities.Using the term loosely,a profit opportunity exists at the toll booths in one line is shorter than the others.The general view of economics is that profit opportunities are rare.At any one time there are many people searching for such opportunities,and as a consequence few exist.

设想你正行驶在3车道的公路上.你遇见了一个收费站设有6个收费亭,其中3个在3车道的正前方,令3个在右手变的不远处,你该选择哪个车道呢?通常有大量的人寻找最短的路线以便使所有线路长度等同.
经济学中的术语“利润”一词有着非常精确的意思.然而,经济学家经常轻率地将无风险的“好生意”或有利可图的投机视为利润机会.轻率地采用该术语,存在于某一路线的收费亭的利润机会比其他路线的要短.经济学总观点就是利润机会罕有.任何时候都有许多人寻找这样的机会,结果却很少存在.
