Nationalism is bad for your health

“Some of the effects of nationalism are obvious, as with the Russian war against Ukraine. Others are more subtle, as when a recent shortage of infant formula in the US was aggravated by trade barriers. In some cases, Americans don’t even know that they are being hurt by nationalism. David Henderson recently pointed out that one factor explaining the low quality of airline service in America is the prohibition on domestic flights by highly respected international airlines, such as Singapore Air. I wonder how many frustrated Southwest Airline passengers are even aware that their government doesn’t allow them to choose foreign airlines? And how many are aware of how the Jones Act contributes to higher prices?” (01/09/23)
