.there are people who are gambling addicts that earn salaries but at the end of the month they lose it all in less than minutes
Well this is true, in fact there are many cases where this type of thing happens and the friends, family of the person reach a moment where they abandon him, because the addiction has consumed him a lot, that is why casinos and sports bets are for adults, because an adult is supposed to control everything and is able to do the right thing, I think that a person that something like this happens to him is because he is mentally not well.
Reality that still happening where a person got too much engage and they are willing to spend their month salary to test their luck against casinos, most of them already experienced both winning and losing and becuase of that experienced they are tend to try aiming to win more or recover from their losses and few may win but the majorities will experienced the same thing and suffer more losses, it's a tough call to bring good solution unless you are capable calling that hard stop when it's barely needed.
