I don't know how you guys connected this topic in a political point of view, but yeah, ALL politicians are selfish. They ran and secure themselves in the office for their own gain. Though, some may not be too obvious because they are doing their job well.
Gambling is one of the few vices that could potentially destroy one's life, career, and even family, but government had a hard time controlling it because it generates huge revenues. That means, huge pocket for the politicians too. So, educating gamblers like these kind of parades won't have any significant results in my opinion.
Most cases on most places on which government wouldnt really be banning out gambling for the sake of their citizens not unless if there's too much noise about gambling addiction and something uncontrollable on which this might be the time that they will be reconsidering on trying out to ban or completely be getting rid out of it. If it wasnt really that imposing any issues or huge concern into their vicinity then it will really be that impossible that they will be totally getting rid of it and as you do mentioned that it does bring out that huge revenue specially that they could milk it out in terms of tax on which if a certain countries does have corrupt officials then it is really that something that will really be that too interesting into their eyes and wont really be letting it slip. Although not all officials will really be having such approach on which there be still those who are doing their jobs on the right way. We do know on how taxes do really being used and having that huge share up in terms of tax because of gambling business revenue then this will really be that helpful in terms of development of a certain country or place. It do really just that only need that moderation and control so that they will really be able to avoid some potential problems later on.
