If as a parent you can protect your growing child from early exposure to negative vices such as gambling and drugs you will have less work to do when they become adults, this is because at an early stage, the child can not stand up for themselves allowing them to get exposed to thing's from the society is somewhat dangerous to their upbringing and this has become a big issue for the bad societal upbringing in the current generations, so clearly I agree with the fact that gambling and drugs are the two major negatives vises that could limit a child proper mental growth.
