People move because of the wear and tear of anxiety. Because of the gnawing feeling that no matter how hard they work their efforts will yield nothing, that what they build up in one year will be torn down in one day by others. Because of the impression that the future is blocked up, that they might do all right but not their children. Because of the feeling that nothing will change, that happiness and prosperity are possible only somewhere else.
Life of Pi by Yann Martel
