No one is saying that innovation doesn't happen in other places in the world, or that the people there aren't brilliant. Only that by evidence of the size and output of the economy in the US, it is the most effective. That may not be true forever, and there have been a great number of words dedicated to making that argument, but it appears to be true today.

What worries me most about the thinking in the US right now is the xenophobia. If there is one thing I'm most proud of, as a citizen of the USA, it's that people want to come here. I want to welcome them with open arms. I want to work hard to make the US the "place to be" for starting a business.
