'America Is Full': An Example of Economic Illiteracy

President Trump's statement that “our country is full” as an argument against immigration is not just reminiscent of one of the darkest periods in human history. It is not just a re-iteration of the foul principle of Lebensraum that justified some of Nazism's worst moments. It is economically wrong. One of the United States' greatest economic assets has always been its willingness – sometimes enthusiasm – to take in people who contribute to economic growth. Throwing away that asset is not just morally wrong; it is bad economics.
