Gambling, corruption, moral degeneracy, and organized crime all go hand in hand. It is practically an immutable law. Now whether governments should be regulating, participating in, or banning such is another matter.
Most are unaware that State sponsored lotteries we're tried across the USA 2-3 generations ago. Many States responded to the destruction and near bankruptcy caused by them, by literally amending thier Constitutions to place bans on the practice. They were ensuring that the mistake would never be made again. In my home state of GA(help me!), a referendum had to be passed to first amend the State Constitution in order to swing back open the State sponsored lottery door.
As the old saying goes, "a generation which ignores it's history is doomed to repeat it". After the societal damage is to far done to undo, the general populace will see the error of our ignorance.
