Everyday Economics: Immigration Economics
University of Rochester economist Steven Landsburg (author of Armchair Economist and More Sex is Safer Sex) poses the following question in his new Slate.com column Everyday Economics:
"How do you justify a border fence? Why is it OK to consign millions of unskilled Mexicans to lives of desperate poverty? I'm told it's because Americans should care more about their countrymen than about a bunch of foreigners. OK, but how much more?
Surely there's some limit; virtually nobody thinks, for example, that Americans should be allowed to hunt Mexicans for sport. So, exactly how much are you willing to hurt a foreigner to help an American? Is a foreigner's well-being worth three-quarters as much as an American's, or half as much, or one-quarter as much?"
Landsburg provides his usual careful economic cost-benefit analysis answering the question, and in the process makes this following point:
"On balance immigrants don't harm Americans; virtually all economists agree that immigration makes us richer, not poorer. Every immigrant is a potential trading partner, a potential employee, and a potential customer. He bids down wages, but that's a two-edged sword: It's bad for his fellow workers, but it's good for employers and good for consumers."
