"Immigration restrictions slow economies, but they don't necessarily prove or portend bigotry or racism. Indeed, it's possible for an American government to restrict immigration and foster national comity at the same time. That's what Presidents Warren Harding and Calvin Coolidge demonstrated in the 1920s." ~Amity Shlaes

"Whether one traces his Americanism back three centuries to the Mayflower, or three years to steerage, is not half so important as whether his Americanism of today is real and genuine. No matter by what various crafts we came here, we are all now in the same boat." ~President Calvin Coolidge

"What Harding and Coolidge sought was a breathing space for all the immigrants to assimilate, time for them to learn English and what people in those days called "Americanism." By Americanism they meant of the familiarity with common law, U.S. civics and adequate workplace English." ~Amity Shlaes

Amity Shlaes points out that immigration restrictions instituted in the 1920s did not result in wage increases as much as "restrictionists had hoped they would. Restriction didn't prevent the Great Depression. When, many decades later, Asians were again allowed to immigrate, they prove their social and economic worth through their contributions many times over."

She then goes on to suggest something that is typically controversial. Read the following passage and think about it. "Defunding the official publicly funded bilingualism of the courts and schools would accelerate Hispanics' move into the professional class. Workers are more flexible and integrate better when there is no language barrier. Official bilingualism directs its own wall, a cultural wall." 

To me, it is clear that this great country is made great by its people and those people come from all corners of the globe. We should celebrate immigration while at the same time acknowledging that free and unfettered entry would carry risks analogous to the Trojan horse.
