Gambling companies have a responsibility to protect children and gambling addicts. They should not advertise on posters in poor towns and villages because people there have money problems. If they advertise in rich cities they should avoid schools and youth clubs. Gambling ads are a part of daily life for people who do not want to gamble.
You are absolutely right, and I would even add that gambling establishments should not only not place their advertising, but moreover, they should prevent even the slightest chance that children from poor cities or villages can become addicted gamblers. And this should be achieved by the fact that schools in such regions should conduct additional courses after school, at least for a few minutes, where the teacher will at least briefly talk about the harmful effects of online casinos or sports betting on immature minds.
I agree with you, if children receive careful education about gambling from their educational institutions, and understand the negative effects of gambling, then they will be motivated to stay away from it.
This can certainly be much more effective, it is necessary to create awareness through the education system to save young people from gambling addiction.
As a result, they will be alert to the negative effects of gambling and want to stay away from gambling, through this system, it is possible to reduce the amount of gambling addiction among minors to a large extent, it will be very effective.
No one can be forcibly stopped from gambling, that is why they have to be educated from within, so that they themselves decide to stay away from it.
