generally all accept that individuals don't buy public goods. They
won't individually go buy clean air. They won't individually go buy
national defense. Collectively, they're willing to pay for them. They
want everybody to pay. They want everybody to share in the burden, and at that
point they say, "Yes, we'll pay for national defense. We'll
pay for clean air." But only a few people will go and pay for clean air
when other people are freely polluting the air. And so we're not able to
rely on individual decisions in the marketplace to clean up the air, to solve
the problem of climate change, to solve the problem of oil dependence. It takes
collective action; it takes government action.
