Do you think gambling companies will get to have enough money, powerful connections to manage what even the tobacco industry failed at, complete domination of advertising in every sport that no country would find a majority in their parliament to even issue a draft law against it?
Imagine that someone in the parliament is a co founder of the casino or is an investor, would it be possible to draft a law against them? definitely not.
In my country, I don't see casinos that much but sportbookies are big players in the economy currently because they sponsor even major national events or projects, if you move to the government residential areas you find it more over there that sport bookies are big part of the decision makers of the economy because how the hell are they more restricted in some activities especially those who partner with the government! but then some are facing real legal issues with government.
So, some of this casino got power either through having relationships with the members of the parliament or having a direct connection with members as investors, co founders or board members of the casino.
