However, other countries simply set high taxes to these activities, which I think is a false morality, as if by paying these activities can be less questionable. (Note: I personally do not question regulated gambling).
Personally I think that religion is a relic of history that should be consigned to the rubbish bin - it should not be influencing rational and logical decisions today. It had a place for comforting people and building some basic laws for society, however we have now advanced far beyond the need for it. Man can judge man, based on changing moral codes and scientific knowledge (smoking used to be "cool" before we really knew the long term damage it could do). Gambling should be treated like any other entertainment business and taxed accordingly. The one thing that I think governments are too lenient on is helping problem gamblers - if someone identifies that they have uncontrollable urges there should be a country, if not worldwide, system that they can click a button to ban themselves for a certain period of time - 3 months, 6 months, 5 years, whatever. The person is taking responsibility and self excluding, the tools to protect them should be there.
