The immigration dilemma

Politically, the open borders rhetoric helps Trump. Even in California, three-quarters of the population, according to a recent UC Berkeley survey, oppose sanctuary cities. Overall, more Americans favor less immigration than more. Most, according to a recent Pew Research Center study, also want tougher border controls and increased deportations. They also want newcomers to come legally and adopt the prevailing cultural norms, including English.

But in his rants on immigration, Trump may be going too far. Only a minority favor Trump’s famous wall, and the vast majority, including Republicans, oppose massive deportations of undocumented individuals with no criminal record. Limiting Muslim immigration does better, but appeals to only roughly half of Americans.

Trump’s restrictionist choice for attorney general, Sen. Jeff Sessions, is also on record opposing more legal immigration. This could prove ruinous to the country’s long-term future. Like most high-income countries, the United States’ fertility rate is below that needed to replace the current generation. If the U.S. cuts off its flow of immigrants too dramatically, we will soon face the labor shortages, collapse of consumer demand and drops in innovation already seen in the European Union and much of East Asia.

An overly broad cutback in immigration would also deprive the country of the labor of millions of hard-working people, many of whom do difficult jobs few native-born Americans would do. The foreign-born, notes the Kaufmann Foundation, are also twice as likely to start a business as the native-born.
