I think almost all countries in Europe and America have legalized gambling, not just limited to the city. We can see that the gambling sites became the official sponsor of the sports club such as soccer, basketball, boxing and so on. In addition, the gambling sites are also free to advertise in a variety of official media, it is certainly beneficial for the country, because it could get taxes from gambling.
