Tom Friedman's comments about immigration in Sunday's paper ("Openness Crucial for U.S. Economic Recovery" on page C9) only takes into account the short run.

In the long run how will openness affect our economy?

The answer to this question depends upon how population changes affect our economy with or without immigration. When average incomes rise, birth rates fall. In fact you might say that the most effective birth control method in the world is per capita income.

Uganda has an annual average income of $1,000 per person. Half of its population is under 15 years old. On the other hand, Japan has an average annual income of $40,000 while fifty percent of Japanese are over 44.

Without immigration, the United States and many countries in the European Union would be losing population. Russia’s population is already declining. China’s one-child policy puts it below the 2.1 replacement rate.

The world will eventually face a severe shortage of young people as it becomes more affluent.

The Japanese are trying to deal with this problem without large-scale immigration by introducing ever more sophisticated robots. Just getting a robot to walk turned out to be quite challenging. It seems unlikely that they will be able to replace highly-skilled people with robots any time soon.

Nations that find themselves losing population may want to reconsider their opposition to immigration if they want their economies to sustain basic services such as Social Security and Medicare.

Progress requires creative people with new ideas who contribute to the payroll tax. Economic studies have shown that immigrants are not random draws from the populations of their home countries. They are self-selected to have imagination, initiative and determination.

Rich countries must accept some significant amount of immigration to avoid sliding backward down the economic ladder.

As highly skilled workers become more specialized, companies become more choosy. It's no longer enough just to have an advanced degree in statistics. A financial firm may need a specialist in state space models while an internet marketing company may want a Bayesian specialist in decision tree models.

Whether the real wage of highly skilled workers goes up or down depends upon whether the rate of specialization and division of labor is greater than the rate of increase in available workers within each ever-more-narrow specialization.

Wages for high tech workers will go up if the division and specialization of labor is occurring even faster than the rate that such workers are becoming available.

America has a history of attracting hard-working and innovative people. While other nations and groups have continued fighting over land elsewhere in the world, the United States quietly has made off with their best and their brightest.

Before 9/11, America led the world in producing both highly educated and highly skilled university graduates. American universities attracted self-selected individuals with exceptional initiative and talent from everywhere.

This has enabled America to acquire the most valuable and productive resource of all. With greater fluidity of labor, openness to new ideas, and better acceptance of people from different cultures and traditions, America has attracted the world’s most creative and productive people.

This is our true comparative advantage.
