The benefits to the host countries are easy to see: Economic migrants often work harder for less money than locals. This is not in everyone’s interest, to be sure: Pointing out the benefits of cheap labor will not persuade people whose wages might be undercut.
对宗主国的好处很容易看得到：经济移民往往工作更卖力，挣的钱还更少。这肯定不符合所有人的利益：指出廉价劳动力的好处不会说服那些工资受影响者。无论如何，即使在德国，接受经济移民总比争取对难民的同情难度要大。
