Situation like this sometimes can make a child to start leaving an unusual lifestyle by stealing from their parents or guidance just to meet up their gambling activities.
If you pay close attention, before opening a casino or gambling account, it is clearly written that no one under the age of 18 should participate in gambling. If gambling or cigarette companies state in their policies that minors should not participate in gambling, it would not be right to directly blame the gambling authorities for the loss of education. If students ruin their valuable careers by participating in gambling on their own, then I would definitely say that it is primarily the fault of the guardian and the student. Why would he participate in gambling while he is still a student?
