The only way to thrive is to innovate. It's that simple.

People used to think that more population was bad for growth. In this view, people are stomachs - they eat, leaving less for everyone else. But once we realize the importance of ideas in the economy, people become brain - they innovate, creating more for everyone else.

Education is the key to the future: You've heard it a million times, and it's not wrong. Educated people have higher wages and lower unemployment rates, and better-educated countries grow faster and innovate more than other countries. But going to college is not enough. You also have to study the right subjects.

The obsessive focus on a college degree has served neither taxpayers nor students well. Only 35 percent of students starting a four-year degree program will graduate within four years, and less than 60 percent will graduate within six years. Students who haven't graduated within six years probably never will.

I utterly reject the view that the Third World is doomed to poverty and starvation. Not only is this wrong, I think this attitude verges on the immoral, like thinking that slavery is an unalterable facet of the human condition so why bother doing anything about it?

It would be really great if I discovered a cure for cancer, but it would only be a little bit less great if my neighbor did. So I am pretty happy when my neighbor becomes wealthier, better educated and more innovative. I feel the same about China and India.
