Europe's list trillion: America's gain from European immigrant entrepreneurs. "The other troubling statistic is the amount of value, and the number of jobs, created in the U.S. by European immigrants. Of the top 25 U.S. public tech companies by market capitalization, 11 were either founded or co-founded by a first- or second-generation European immigrant. Looking just at first-generation Americans, six companies had founders whose parents left Europe. Taken together those six companies generated $534 billion in market capitalization in the U.S., and in the process generated 242,000 jobs. If you add in the market capitalization from companies whose founders had at least one grandparent who was European, that is another $516 billion; making a total of nearly a million jobs and more than $1 trillion created in the U.S. from European founders. Is it worth considering how much of that value would have been created if their parents or grandparents had stayed home? http://blogs.wsj.com/tech-europe/2013/05/30/europes-lost-tech-1-trillion/
