I do agree with you mate people who made this rule must be crazy when they clearly know that gambling is not good for even teen agers as they can not handle the lose of their money we should not put our young generation in this kind of activities. Better let you children grow mentally then let them gamble and ask them to learn how to gamble first then enter casino.
I think they're just very confident in their education system that's why they thought that through education and learning systems, kids will understand the advantages and disadvantages of money. Obviously, even until now, there are many flaws and holes on the education system, it keeps developing and improving until we reach the peak of gaining knowledge.
But personally, even the child has knowledge through the whole art of money, the temptation to gamble and lose a good future is very high. So it's not recommendable for me even for college students who still getting taking their undergrad, they shouldn't gamble.
Financial literacy has not been taught to kids in school and the students don't have an idea about personal finance. Without knowing how to control personal finance, it is hard to imagine responsible gambling from the same students. The knowledge factor is the main case for controlling the money activity during gambling but no one can swallow the loss without the emotional reaction, honestly.
