Migration is one of the most powerful forces shaping civilization. At this moment, 191 million people live outside the countries of their births, and the movement has accelerated. Why is this transnational migration so significant? Because the values, demographics, and assets of the people within a nation determine its character. As wealthy nations with shrinking native work forces, the countries of Europe and North America have been trying to preserve their national cultures while reaping the economic benefits of large-scale immigration. In some places, these countries have found that even the economic implications are not solely beneficial, as more immigrants than expected fall into their “social safety net.” That’s why the hottest political topic in both Europe and America is immigration. What’s causing this? What are the implications? And, what is the likely outcome? We’ll give you the insights you need.
