Forbes columnist Shaun Rein tries to work out the economic costs of airport security. If 650 U.S. passengers get to the airport an hour early due to heightened security, their lost productivity over the course of a year is $14.3 billion (valuing the U.S. gross domestic product at $23 per worker, per hour). Rein says he is "all for extra security," so long as the extra procedures actually make us safer. "Could something else be done to keep us safe without so diminishing our productivity?" he wonders.
