Those who are long on indignation and short on economics may say that these hotels were now "charging all that the traffic will bear." But they were probably charging all that the traffic would bear when such hotels were charging $40 a night.
The real question is: Why will the traffic bear more now? Obviously because supply and demand have both changed. Since both homes and hotels have been damaged or destroyed by the hurricanes, there are now more people seeking more rooms from fewer hotels.
What if prices were frozen where they were before all this happened?
Those who got to the hotel first would fill up the rooms and those who got there later would be out of luck -- and perhaps out of doors or out of the community. At higher prices, a family that might have rented one room for the parents and another for the children will now double up in just one room because of the "exorbitant" prices. That leaves another room for someone else.
Someone whose home was damaged, but not destroyed, may decide to stay home and make do in less than ideal conditions, rather than pay the higher prices at the local hotel. That too will leave another room for someone whose home was damaged worse or destroyed.
In short, the new prices make as much economic sense under the new conditions as the old prices made under the old conditions.
It is essentially the same story when stores are selling ice, plywood, gasoline, or other things for prices that reflect today's supply and demand, rather than yesterday's supply and demand. Price controls will not cause new supplies to be rushed in nearly as fast as higher prices will.
None of this is rocket science. But Justice Oliver Wendell Holmes said, "we need education in the obvious more than investigation of the obscure."
