Is totally wrong for a father (Parents) not to nurture their children properly before exposing them to money, this is were most parents got it wrongly. At first you must give your child a mentality that making money is very hard and you Must spend money wisely without living a wasteful life for that i don't have to lay any blame on the child rather his parents for living a wasteful live. Believe me or not., as a child you have approximately 35 to 40 percent your father's character and 25 percent of Mothers character while the rest are inborn or a self developed characters due to bad friends or environmental factor. So whatever father does definitely his son must copy it if the father didn't hide himself in most cases, and he just displayed the true nature of the father.
So lastly, we don't have to allow our children to live a life without proper control and caring, despite how wealthy the parents may be, and should be restricted from gambling if not 18 year or more. I wonder what he would become in 10 to 20 years time to come.
if his father is still alive and still has wealth, it is possible that such juvenile behavior will continue, even into adulthood. when working, he will only spend his money doing the same extravagant activities.
every parent has bad traits. but his parents have to cover up his bad nature. so that it does not become something that is commonplace and can be done by children.
the case described by the OP seems to be purely the parent's fault in implementing parenting. Situations like this are common in rich families. more precisely, in children who do not get much time for parents to talk to each other.
