While it is true that addiction can happen the majority of the gamblers can enjoy it without suffering any bad effects on their lives and if anything I will be more worried about people being addicted to their smartphones than gambling addiction as it is way more common, also in most countries people are considered to be adults at 18 years old so it is impossible to stop them from gambling if that is what they want to do, unless you propose that age is pushed even farther back which I do not think it is going to be very popular among the young population.
Could you please underline this claim with facts? This thread should be based on facts rather then based on beliefs. So do you know about a study stating that the majority of gamblers can enjoy it without suffering?I do not have such statistics (although I would look at it with interest if someone provided the relevant research), but I can assume that if a significant number of gamblers suffered from their addiction, then gambling would be prohibited everywhere. By the way, would it be nice if you first clearly defined what you mean by suffering? The range of this concept is quite wide.
I agree with that, however, that number might only be a small percentage only if compared to the total number of people who are gambling, the reason why gambling platforms still exist and in fact, their industry is improving and continue to be one of the most lucrative business on earth. Gambling addiction is a gambler's fault, not on the gambling site.
We can not yes just blame gamblers. But I would say, addiction depends on its existence. I mean, as long as either gambling sites, tobaccos, alcohols and etc are available, none can be stopped from utilizing / using it. So, in other words, their existence is a kind of temptation to use though. I remember, early in 90s, lotteries were sold and many were addicted to it. But now they are all stopped in many places and this diverted its users to other activities. So, everyone is responsible for addiction and not only who gambles.
But a lot of people behave like this and it suits them, they consider such spending to be acceptable. I think the majority of casino visitors think the same - it's simple spending on entertainment, not dumb money.
