As Joseph Stiglitz recently pointed out, it is unlikely that Hitler would have come to power in Germany if the unemployment rate was not 30% at the time. It does not help when some of those trapped in the poor ghettos surrounding major cities – however small a minority – become tempted by violence and fall prey to terrorist recruiters.
世道艰难时，移民和少数群体很容易成为目标。约瑟夫·斯蒂格利茨（Joseph Stiglitz）最近指出，如果当年德国失业率没有高大30%，希特勒就不会上台。大城市周边的贫民区的一些人——不管他们人数多么少——被暴力所引诱加入恐怖组织也绝不可能是是件好事。
