Thomas Friedman makes the case for math and science education and stimulating technological innovation in addition to infrastructure and green job development:

If we spend $1 trillion on a stimulus and just get better highways and bridges — and not a new Google, Apple, Intel or Microsoft — your kids will thank you for making it so much easier for them to commute to the unemployment office or mediocre jobs.

Barack Obama gets it, but I’m not sure Congress does. “Yes,” Mr. Obama said on Thursday, “we’ll put people to work repairing crumbling roads, bridges and schools by eliminating the backlog of well-planned, worthy and needed infrastructure projects. But we’ll also do more to retrofit America for a global economy.” Sure that means more smart grids and broadband highways, he added, but it also “means investing in the science, research and technology that will lead to new medical breakthroughs, new discoveries and entire new industries.”
