One of the main responsibility of the government is to make a country livable and making it secure into its citizens on which it will really be that a huge problem if they would really be able to see gambling addiction related kind of crime on which this has been caused by too much addiction due to uncontrollable gambling businesses that resides or available on such country. Whereas, the government will neither be making out some decision whether they will really be that still allowing it or would be making out such step on banning it out because of the effects that it do brings up. If they would really be prioritizing about taxation and revenue that it does give on a certain country then they wont really be caring about addiction then there's nothing we can do about it. Actually addiction is something a problem which is really that personal and if it turned out to be severe then this is where potential problems would really be rising and thats why on the moment that it will happen into you then it will really be normal that you should really be doing on what the things that must be done.
You are really indeed having that common sense whether you are still doing the right stuff or not. It is really just there are individuals who are really that good on controlling things and able to avoid addictions.
Before the government take decision, they must research everything so they will not make a wrong decision and will give a bad effect to their people. They can get the income from all businesses in their country but they should discuss it with all elements so all regulations that they create will gives a positive effect to their country. Related to gambling, the government should research the impact to their people and make communication to many people so they know what is happen to their citizen. If they think that gambling can gives a bad effect to their citizen, they may strictly their regulations and not tolerate if people who doesn't 18+ playing gambling.
You are wrong my friend, it will affect them, the higher the tax, the higher the discouragement, this is normal economics everywhere in the world. Though some ardent gamblers and the addicted ones may continue to gamble all the same, the percentage of those who were supposed to gamble must have drastically reduced. Taxes have reasons beyond the government's revenue target, it also dissuades people from those activities. Imagine the government of a country increases the taxes to about 85%, do you think the majority of people will continue? Of course not. People mostly gamble for money but if they can only earn 15% of the money they narrowly win, what is the point of gambling?
They can continue playing gambling but will not show to many people to avoids the tax. You can see many people avoids tax even they are not playing gambling and running a clear business. They think that tax only reduce their profit and they want to have that money for their own interest.
That can happens to gamblers where they will still playing gambling without paying tax if they win because they know how to hide their winning. Tax should be impose but the officers who does their job must be clear from any illegal things so the tax can be distribute to the right place.
