结构性失业通常来源于技术变革。

　　If the introduction of DVD players cause the sales of VCRs to plummet, many of the people who manufacture VCRs will suddenly be out of work.

　　如果DVD机的出现让VCR的销量暴跌，那么很多生产VCR的人就会突然失去工作。

　　By looking at these three types of unemployment, we can see why having some unemployment is a good thing.

　　看了这3种失业形式之后，我们就能明白为什么适当的失业率是好的了。

　　Most people would argue that since cyclical unemployment is the by-product of a weak economy, it is necessarily a bad thing, though some have argued that recessions are good for the economy.

　　很多人可能会说：由于周期性失业是经济疲软的副产品，所以它肯定是个坏事，虽然也有人说衰退对一个经济体来说有好处。

　　What about frictional unemployment? Let's go back to our friend who quit his job as an economic research to pursue his dreams in the music industry.

　　那摩擦性失业呢?我们再来看看刚刚那位辞掉经济学研究员工作转而投身音乐界的朋友。

　　He quit a job he disliked to attempt a career at the music industry, even though it caused him to be unemployed for a short while.

　　他辞掉了一份自己不喜欢的工作，转而寻求一份音乐界的工作，即使短暂失业也在所不惜。

　　Or consider the case of a person who is tired of living in Flint and decides to make it big in Hollywood and who arrives in Tinseltown without a job.

　　或者我们来想象一个厌倦了在小城弗林特生活的人，他决定去好莱坞寻求飞黄腾达的机会，于是以失业状态来到了浮华城。

　　A great deal of frictional unemployment comes from people following their hearts and their dreams.

　　很大一部分摩擦性失业都是源于人们追寻自己的性子和梦想。

　　This is certainly a positive type of unemployment, though we would hope for these individuals' sakes that they do not stay unemployed for too long.

　　这当然是一种积极型的失业，不过我们希望这些人不要失业太久。

　　Finally, structural unemployment. When the car became commonplace, it cost a lot of buggy manufacturers their jobs. At the same time, most would argue that the automobile, on net, was a positive development.

　　最后，结构性失业。当汽车成为常态的时候，很多马车制造业的人失去了工作。而同时，大多数人会觉得自动化汽车从总体上来讲是个积极的发展方向。

　　The only way we could ever eliminate all structural unemployment is by eliminating all technological advancement.

　　要消除所有的结构性失业，我们只能消除所有的技术进步。

　　By breaking down the three types of unemployment into cyclical unemployment, frictional unemployment, and structural unemployment, we see that an unemployment rate of 0% is not a positive thing.

　　在把失业拆分成周期性失业、摩擦性失业和结构性失业之后，我们可以看出来，零失业率并不是一件好事。

　　A positive rate of unemployment is the price we pay for technological development and for people chasing their dreams.

　　一点正向的失业，是我们为技术进步与逐梦自由付出的代价。
