Open Borders: The Science and Ethics of Immigration by Bryan Caplan
My rating: 5 of 5 stars
An excellent presentation of the economic and moral arguments for open borders. Zach Weinersmith's (of SMBC comics) wonderful art makes the arguments more interesting and more approachable. Caplan doesn't just give his argument. He takes seriously the most influential arguments against open borders. He gives his reasons for rejecting these arguments, but never merely dismisses them.
