Instead of outrightly banning gambling, how about if the concerned countries officially include gambling education in their academic syllabus, just like sex education is taught in schools. Gambling education will teach the young ones the dangers of gambling and promote moderation in gambling. Will this not be a better way to handle the gambling cases?
It is a good idea and the government should do that but it's not a guarantee that the educated gambler will not get himself into addiction, addiction victimizes many people regardless of their race, profession, or educational attainment, I even read about gambling counselors getting into addiction.
The government will always look at the data if they see an abnormal surge they will take action and ban gambling even if there are group and school counseling about gambling addiction.
The government cannot tolerate a high number of people going into addiction, because the morale of their society is going down, a high number of addicted gamblers means the crime rate will be high, crime is always associated with addiction and the government must stop it.
