Markets in everything?
Government officials insisted they were putting forth their best efforts and pleaded for patience, saying further help was on the way.
I swear that this is a desperate suggestion, not an attempt to make a political point, but:
The government's best efforts, to this point, are not getting New Orleans evacuated. What if W, or the governor, got on TV and and announced that anyone with available, ventilated transportation would be paid $500 for every person they evacuated from the city? Pick 3 checkpoints 20 or 40 miles outside the city, and let the charities or whoever take over from there.
I suspect there would be trucking companies cutting windows in their trailers with axes toute suite and hiring people to ride shotgun, in the original literal sense. I also suspect there would be fraud, abuse, and other horrible unintended consequences, including some people being shot indiscriminately. But weighed against the status quo, which appears to be thousands of people starving, dehydrating, and dying in the streets of New Orleans while patience is requested, I think the "lack of organization" inherent in such a plan doesn't look so bad. If there's going to be anarchy, let's have lives saved, instead of lost, as a consequence.
