Typically, development experts regard migration as a sign of failure: if development policies work, people should not want to move. Accordingly, migration has been viewed as a problem to be solved –&#160;not as a solution to a problem.
发展专家往往将移民视为一种失败：如果发展政策奏效民众应当不想移民才对。因此，移民一直被视为需要解决的问题，而不是解决问题的手段。
