To oil the city life, a diverse array of approaches have been put forward, the most striking among which is that governments should encourage the city dwellers to move to small towns or cities. The motivations of those who advanced this suggestion are nothing wrong. But this proposal per se is not plausible. For one thing, it is impossible to know who should move. That is to say we do not have a reliable criterion against which governments may decide who should migrate and who should stay. For another, it is difficult to calculate how many should move. |
