Jason Riley’s Let them In: The Case for Open Borders
This book expounds on two general themes. The first is that, contrary to received wisdom, today's Latino immigrants aren't "different," just newer. the second is that an open immigration policy is compatible with free-market conservatism and homeland security. I explain, from a conservative perspective, why the pessimists who say otherwise are mistaken. I argue that immigrants, including low-skill immigrants, are an asset to the United States, not a liability. Immigrants help keep our workforce younger and stronger than Asia's and Europe's. As entrepreneurs, they create jobs. As consumers, they generate economic activity that results in more overall economic growth. By taking jobs that overqualified Americans spurn, they fill niches in the workforce that make our economy more efficient and allow for the upward mobility of the native population.
An immigration policy that acknowledges these economic realities would provide more, not fewer, legal ways for immigrants to enter the country.
