I’ve been thinking a lot lately about Tom Brokaw’s book “The Greatest Generation,” that classic about our parents and their incredible sacrifices during World War II. What I’ve been thinking about actually is this: What book will our kids write about us? “The Greediest Generation?” “The Complacent Generation?” Or maybe: “The Subprime Generation: How My Parents Bailed Themselves Out for Their Excesses by Charging It All on My Visa Card.”

Our kids should be so much more radical than they are today. I understand why they aren’t. They’re so worried about just getting a job or paying next semester’s tuition. But we must not take their quietism as license to do whatever we want with this bailout cash. They are going to have to pay this money back. And therefore, we have an incredibly weighty obligation to make sure that we not only spend every stimulus dollar wisely but also with an eye to creating new technologies.

We not only need to bail out industries of the past but to build up industries of the future  to offer the kind of big thinking and risk-taking that transforms enormous challenges into world-changing opportunities. That is what made the Greatest Generation great. This money can’t just go to patch up our jalopies.

“Remember, this money will not be neutral,” said Andy Karsner, a former U.S. assistant secretary of energy. “We are talking about directing an unprecedented volume of cash at our housing, energy, transportation and infrastructure industries. This cash will either fortify the incumbent players and calcify the energy status quo, or it will facilitate the economic transformation we seek. The stimulus will either be white blood cells that will heal us or malignant cells that will continue to sap our strength.”
