I have a friend that works for an IT Disaster Recovery company and they were receiving stuff from various company's in NO with no PO's, just notes saying please restore, we don't care how much it costs.
A couple of IT companies I follow, no need to mention names, are already heavily involved in restoring service. A lot of money is being spent already, $1 billion per day, on recovery, and beginning rebuilding is still several months away. Some are going to get significant boosts to their business, and [this is important] without even a hint of gouging.
Exactly. Henry Hazlett pointed out that a broken window does generate economic growth---fixing the window, more police, lumber/glass sales---but at the expense of other stuff we would be doing with that money (more productive.) So I think there will be a boom, but I think that it would have been even better, obviously, without the hurricane.
