"Immigrants have historically provided one of America's greatest competitive advantages. They have come to the United States largely to work and have played a major role in the country's recent growth. Between 1990 and 2007, the proportion of immigrants in the U.S. labor force increased from 9.3 percent to 15.7 percent.
Approximately 45 percent of the growth of the work force over this period consisted of immigrants. Moreover, a large and growing proportion of immigrants come with high levels of education and skill.
They have contributed disproportionately in the most dynamic part of the U.S. economy - the high-tech sector. Immigrants have co-founded firms such as Google, Intel, eBay, and Yahoo.
And immigrant inventors contributed to more than a quarter of U.S. global patent applications.
While I really wish America and Europe very well, I think it is hard to deny that the current turn inwards and against skilled immigration will only serve to accelerate the inevitable. The next 50 years of entrepreneurial innovation will belong to India. The Silent Revolution about which I have written before is well underway.
