Most of the countries actually putting bans on gambling are for religious reasons and that's why it's mostly the middle east region although it's not entirely pin on those areas but I think you get the picture. Other countries are actually utilizing the massive gambling industry which is something that the government are well known for as they always exploit situation to their benefits and one way they achieve this is by taxing the gambling industry which active initiative towards this.
And they are right not to ban casinos, but to give the green light for further development of this industry. If the government of the country is wise and far-sighted, then this is a wonderful decision that will give the treasury additional income. What religious beliefs can there be when the state is on the verge of extinction. This practice should be taken into account by those who have no natural resources, and not constantly fight with their neighbors.
