Man, gambling do not create added value products, so it's the worst idea to allow more casinos after crisis. You just froze situation in time, because people will gamble, lost their money and will not invest it in better things like own business or consumption.
Casinos it's zero sum game, and after crisis you need something which will increase wealth of all participants (non zero sum game). For example, deregulate business opening schemes and so on.
Why you always assume that gamblers are always going to lose money? In gambling, when someone loses his game, there is someone on the other side who is credited with a win. So the net loss is near zero. On top of that, a part of the waged amount ends up as the casino commision and government taxes, helping in employment creation and government revenues.
