Open Borders: The Science and Ethics of Immigration

Open Borders: The Science and Ethics of Immigration by Bryan Caplan and illustrated by Zach Weinersmith

Bryan Caplan is professor of economics at George Mason University, a research fellow at the Mercatus Center, an adjunct scholar at the Cato Institute, and a self-described "economic libertarian". In Open Borders he presents the case for worldwide open borders. He argues that opening all borders would eliminate poverty and usher in a booming worldwide economy, greatly benefiting all humanity.
If you are concerned about the restrictive immigration policies of rich countries, this book will provide you with compelling arguments against them. If you are worried that open borders would bring ruin to first world countries, maybe this book will assuage your fears.
Both economic and moral arguments are brought forward to show how opening all borders would make this world a single prosperous place to live and eradicate poverty and the crime associated with it. Caplan spends a good portion of this book addressing the potential criticism to his theories, making it a well-balanced presentation of what some may consider a radical idea. Wonderfully illustrated by Zach Weinersmith, this book is accessible to people with little or no background in economic theory.
