In total, every dollar spent on increased migration would produce more than $45 of social good – possibly more than $300. While in today’s political climate, increasing migration might be difficult to achieve, it is worth pointing out how effectively it could help the world’s poorest.
这样的移民对发展中国家也非常有利，因为外来务工人员能将挣来的报酬汇回家去。总的来讲，每耗费一美元扩大移民就能产生超过45美元——甚至可能超过300美元的社会效益。尽管扩大移民在当今政治气候下或许难以实现，但应该指出移民对帮助世界最贫困人口多么有价值。
