The hidden hand of the market will never work without a hidden fist -- McDonald's cannot flourish without McDonnell Douglas, the builder of the F-15. And the hidden fist that keeps the world safe for Silicon Valley's technologies is called the United States Army, Air Force, Navy and Marine Corps.

If I were advising President Obama, since he's the one running, I would have made his campaign very simple. I promise that in four years, I will get more Americans, as many as I possibly can, the opportunity and access to some form of post-secondary education. I want more of them to graduate high school with the skill-set of post-secondary education and I want more of them to be able to obtain that post-secondary education. This is the only way we are going to close the income gap.
