Lots of people think that government mandates create new jobs, net net. It's a key different assumption between those who think government should do more, vs. those who think they should do less. See the short video on Bastiat(2 minutes). Some great quotes by Keynesians:
"..the terror attack .. like the original day of infamy, which brought an end to the Great Depression -- could even do some economic good."
~Paul Krugman, NYT, 9/14/2001
"...economically the net result of the terrorists's actions is likely to be beneficial to the United States.'
Tim Noah, Slate, 9/12/2001
"Despite the devastation, experts said today that in some ways the earthquake [in Kobe Japan] could give a boost to an economy struggling to recover from a long recession."
Nicholas Kristof, NYT, 1/18/95
