I think it's "boring life needs gambling"? Most of the gambling is from a game, a contest, it just so happen that they have to put a bet. Gambling is already part of the culture of so many people, it is already in their culture, any contest, that would amuse everyone, people will bet on it.
But gambling before is not as vicious as it is today. people value their money and properties too much before that if they are going to bet, it should be on something that is memorable and most of the time they themselves are at stake, and not just for the sake of raking money.
Yeah, a lot of people have imbibed gambling to be a normal thing that every little thing they want to do, the first thing that comes to mind is to try to gamble. The reason why gambling has become so vicious today is just simply because nowadays people just want to get rich quickly and then they end up looking for the wrong answers to their predicaments in the wrong places but in general, except personally I would not consider it a culture rather than just an additive disease. I may sound nonsense but that is the reality as per my experience, a complete different one from what others usually do share.
