College has been oversold. It has been oversold to students who end up dropping out or graduating with degrees that don't help them very much in the job market. It also has been oversold to the taxpayers, who foot the bill for subsidies that do nothing to encourage innovation and economic growth.

Capitalists work hard to produce what consumers want. Artists who work too hard to produce what consumers want are often accused of selling out. Thus, even the languages of capitalism and art conflict: a firm that has 'sold out' has succeeded, but an artist that has 'sold out' has failed.

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.

It used to be that almost all innovation came from the U.S. and a small number of other developed countries. That's no longer the case, and as China and India grow, it's changing even more. Expect a lot more Chinese and Indian Nobel prizes in the future.
