Here’s my fun fact for the day, provided courtesy of Robert Litan, who directs research at the Kauffman Foundation, which specializes in promoting innovation in America: “Between 1980 and 2005, virtually all net new jobs created in the U.S. were created by firms that were 5 years old or less,” said Litan. “That is about 40 million jobs. That means the established firms created no new net jobs during that period.”

Message: If we want to bring down unemployment in a sustainable way, neither rescuing General Motors nor funding more road construction will do it. We need to create a big bushel of new companies  fast. We’ve got to get more Americans working again for their own dignity  and to generate the rising incomes and wealth we need to pay for existing entitlements, as well as all the new investments we’ll need to make. It was just reported that Social Security this year will pay out more in benefits than it receives in payroll taxes  a red line we were not expected to cross until at least 2016.

But you cannot say this often enough: Good-paying jobs don’t come from bailouts. They come from start-ups. And where do start-ups come from? They come from smart, creative, inspired risk-takers. How do we get more of those? There are only two ways: grow more by improving our schools or import more by recruiting talented immigrants. Surely, we need to do both, and we need to start by breaking the deadlock in Congress over immigration, so we can develop a much more strategic approach to attracting more of the world’s creative risk-takers. “Roughly 25 percent of successful high-tech start-ups over the last decade were founded or co-founded by immigrants,” said Litan. Think Sergey Brin, the Russian-born co-founder of Google, or Vinod Khosla, the India-born co-founder of Sun Microsystems.
