Lol the money moves to government through taxation and then vanishes while they continue to tax everyone all together

doesn't matter if less-privilege or rich . Normally, taxation wasn't meant to benefit the less-privilege only, it benefits the country at large but yeah it should benefit them the more because the rich can find a means to get those resources /services...
Besides, not only the less-privilege bets on casino( although the rate is more compared to the rich) so the it's not like everything comes from the less privilege to the casino..
