Quote of the Day: Externalities

From Tyler Cowen, on whether the TSA's new full body scanners are worth it:

Keep in mind there are significant negative externalities from exploding airplanes.

Don't you just love reading economist bloggers? In any case, there's more at the link, and Tyler suggests that if Americans really want to get outraged over something air related, they should get outraged over the "lack of markets in allocating scarce resources," and "airlines which ruthlessly screw you over, repeatedly, and lie to you and mistreat you." Roger that.
