One of America's strengths

From salon.com:

Twenty-five percent of the technology and engineering companies started in the United States between 1995 and 2005 had at least one key co-founder who was an immigrant, reports a new study from researchers at the Pratt School of Engineering at Duke University. The researchers estimate that these companies generated $52 billion in sales and employed 450,000 workers.
