Conventional economic thinking tells us that people go where the jobs are. In America, there is a long history of westward expansion in search of opportunity. In the UK, Margaret Thatcher’s employment secretary, Norman Tebbit, was fond of telling people about his father who, when unemployed, “got on his bike and looked for work, and he kept looking till he found it.” Clearly, it is easier to find work when you are mobile. But what happens when people can’t or won’t move to where the jobs are?
經濟常識告訴我們,哪裏有工作,人們就會去哪裏。美國有到西部去尋找機會的悠久歷史。在英國,瑪格麗特•撒切爾(Margaret Thatcher)的就業事務大臣譚百德(Norman Tebbit)很喜歡和別人說,他的父親失業後「騎上自行車去找工作,一直找,最後找到了」。顯然,人能夠四處流動,就更容易找到工作。但如果人們無法或不願搬到有工作的地方怎麼辦?
