Recently many countries around the world are now introducing gambling taxation on it citizens and even charging betting houses and casino's some amount of money to operate within it jurisdiction, and recently my country just introduced a 5% Revenue sharing and taking from both betting houses and gambler's winning and this news make me to ask why the government takes such money from gambler's but won't protect the gambler when their is troubles with the betting house.
Because we have loads of cases where gambler's win some huge amount of money and the casino refusing to pay and when reported to the authority you here such things like the casino is not licenced by them or they don't have control over the casino case, the government is only interested in the tax and not protecting the interest of it citizens.
Maybe I'm wrong, but from what I've seen, in most countries when they charge taxes on gambling, they are counting on charging taxes to casinos that have a license in that country and know that the casino has a physical office in that country. Because it's not just the player who pays taxes. The casino will also pay taxes, the casino employees will also pay taxes and the casino will have to respect the country's labor laws. Now, about this issue of someone winning and the casino refusing to pay and that person having no way to complain to any government. This happens when the casino does not have a physical office in the player's country.
