I don't see gambling as a problem no matter how much you lose until you can't do with our it and that's when it has become an addiction gambling only become a problem at the point of addiction because when you become addicted you can't do with our betting and it's a dangerous thing at this stage
Of course when someone become a compulsive gambler, that's when the problem starts because at that point in time they totally lose control of how responsible gambling feels and how to even go about it. If a gambler is spending just the amount of money that they can afford to lose everyday in gambling, that's their decision, it could be a problem for others but not to them and that's not a general problem until the person really go against their decision to spend a huge amount that they can not afford to lose.
