I am a teacher and I am proud of it. At Cornell University I have taught primarily undergraduates and indeed almost every year since 1966 have taught first-year general chemistry.

Today over half of China's undergraduate degrees are in math science technology and engineering yet only 16 percent of America's undergraduates pursue these schools.

Engineering undergraduates should not be charged fees. They should receive grants not student loans and the government will get the money back long-term from increased exports.
