Personally, I believe gambling should be seen as a game, not a habit or an easy access to wealth, " using son as a bet" is the height of it, People should learn about gambling before they start, the same way we learnt about careers, we should learn the act of gambling.
Even those who are experienced in gambling and those who have turned out to be a shame to the system didn't just wake up and jump into gambling.
I believe most of them went through some online tutorship or by just reading and studying the errors of other gamblers, which should set out good habits for them to kick up with, but most of them just set themselves up the way they want, and even if they have a personal teacher, some of them have outgrown them and set their own rules.
