It should be that no politician should get involved with gambling be it as a gambler or as an operator or businessman that focuses on it. That goes against the rule of law that they're lawmakers and they can make laws favoring their business which is all about gambling that can give them even incentives instead of punishments. This should go with their principles and while there's really a big tax that comes from the gambling industry, let it be alone managed by those that have no political interest.
I mostly agree on your post. But if we want to have a free and fair society where all people have the same rights, then it would not be fair for politicians to be forbidden to gamble.
I am okey with them doing whatever they want with their own money that they have earned through their job as politicians, however, they should be closely audited and in case some of them show any signal of becoming a person with addiction for gambling they should be isolated from the public treasury immediately and their political power, so they would not be able to abuse it to get more money to gamble.
Gambling is a question of civil liberties, in my humble opinion.
unfortunately things are not that simple, what has happened is the following:
Party Z politician creates a casino. his party governs the country, he does not pay taxes and does not declare all his assets as required by law in many countries, so he launders money and shares the profits with some members of the government and his political party, when some police decide to investigate the casino, he soon talks to the president of the country and the minister of security and they fire the policeman on the same day, the courts are blind and dumb, they pretend that they are not seeing anything, most of the party members his politician play in his casino
this is part of the scheme to make it appear that his casino has many customers and the money he has comes from the casino's profit, when in fact the casino has the objective of laundering the money from corruption and drug sales, when some newspaper suspects of something and publishes these suspicions, the owner of the casino hires an auditing company that is linked to a member of his political party, sometimes they even accept companies outside the country, but when the foreign auditing company arrives in the country, they offer high bribes and the auditing company presents a report that says the casino is clean, fair and has no involvement with corruption and drugs and everyone outside the country believes it and that's it, matter closed
