Government investment unlocks a huge amount of private sector activity, but the basic research that we put into IT work that led to the Internet and lots of great companies and jobs, the basic work we put into the health care sector, where it's over $30 billion a year in R&D that led the biotech and pharma jobs. And it creates jobs and it creates new technologies that will be productized. But the government has to prime the pump here. The basic ideas, as in those other industries, start with government investment.
