Migration is, of course, part of the adjustment mechanism that makes America work as a single market with a single currency. Even more important is the federal government’s role in helping states that face, say, high unemployment, by allocating additional tax revenue to them – the so-called “transfer union” so loathed by many Germans.
当然，移民正是美国调节机制的一部分。它使得美国能够以使用单一货币的统一市场的形式来运作。更为重要的是：联邦政府通过分配更多的额外税收来缓解各州面临的问题（如高失业率）时所扮演的角色，即所谓的“转移联盟”，让很多德国人深恶痛绝。
