Book Review: Let Their People Come: Breaking the Gridlock on Global Labor Mobility by Lant Pritchett.
This book is primarily written for economists and academics in related fields, but most of it can be understood by an average person.
I was a little hesitant to read this book because I suspected it would do little more than reinforce my existing beliefs. There were certainly parts of the book that I would have been better off skipping for that reason.
But one important effect of the book was to convince me that the effects on the poor of migration to wealthier countries is so large compared to things like “foreign aid” and free trade that anyone trying to help the poor by influencing government policies shouldn’t spend any time thinking about how to improve “foreign aid” or trade barriers.
I’ve long been wondering how to respond to remarks such as Jimmy Carter’s ‘We are the stingiest nation of all’ based the U.S.’s low “foreign aid” to GDP ratio. Pointing out that “foreign aid” is mostly wasted or even harmful requires too much analysis of lots of not-too-strong evidence. Pritchett shows that the wealth affects of allowing the poor to work in rich countries should dominate any measure of how those rich countries treat the poor. By that measure, adjusting for country size, the U.S. ranks better than countries in the EU, but is embarrassingly callous compared to the United Arab Emirates, Kuwait, and Jordan.
The book addresses both moral and selfish arguments for restricting immigration. It treats the selfish arguments (even those based on myths) as problems that can’t be overcome, but which can be reduced via compromises. These pragmatic parts of the book are too ordinary to be worth much.
The sections about moral arguments are more powerful. He clearly demonstrates a large blind spot in the moral vision of those who think they’re opposed to all discrimination but who aren’t offended by discrimination on the basis of the nationality a person was assigned at birth. But he exaggerates when he claims that nationality is the only exception to a widely agreed on outrage at discrimination based on “condition of birth”. Discrimination based on date of birth still gets wide support (e.g. the drinking age). And if you’re born as a conjoined twin, don’t expect much protection from surgery that looks about as moral as brain surgery designed to cure a child’s homosexuality should.
Perhaps this book is one small step toward creating a movement with a slogan such as “Tear down that kinder, gentler Berlin wall!”.
