From the Claremont Review of Books:
* Garett Jones has written a scandalous book. The Culture Transplant: How Migrants Make the Economies They Move To a Lot Like the Ones They Left reviews a generation of social science research on why some countries prosper economically and enjoy good governance while others do not. Jones shows that countries that have a long history of advanced governmental structures and have adopted agriculture early tend to do better. But even more powerful predictions include the number of individuals whose ancestors lived in technologically advanced societies in the year 1500—and these societies tend to be European and East Asian.
* As Jones concludes, “[I]f the only thing you knew about each nation on the planet was the fraction of that nation with ancestors of European descent, and you did the best job you could trying to predict average modern income per person using just that fact, you’d be able to predict two thirds of all global income differences.”
* Peoples matter more than governments or institutions—or, as Jones claims, deep cultural determinants transmitted by families are the most powerful predictors of current national wealth and sound government.
* Next, he asks whether cultural diversity promotes economic growth and good governance. Business management literature shows that culturally diverse work forces are less effective, though skill diversity aids economic growth. As Jones relates, the relevant sociological literature, particularly the work of Robert Putnam, shows that cultural diversity degrades social trust, leading to weaker civil society, lonelier people, and possibly less effective government. Finally, Jones examines the endemic nature of racial and ethnic conflict. Cultural diversity is not necessarily our strength.
Using Jones’s own empirical predicates, immigration skeptics might argue that immigration to wealthy countries does not improve the economic well-being of those already living there. Further, increased cultural diversity could weaken countries economically, degrade social trust and civil society, and raise the always prevalent threat of civil strife.
* immigration creates less cohesive, lonelier societies, which are also poorer, at least on a per capita basis… Degrading civil society is an enormous tax on individuals. People who are less connected—who are not active in church groups, local sports clubs, or simply have fewer friends—live diminished lives.
