There are currently 13 states that have legalized gambling and they have over 450 casinos between those states, and they bring in 72 billion dollars a year.
From this money states get extra money for road repair, schools and many other things that a state needs money to fix and maintain.
In the last 10 years there have also been a large number of Indian casinos being granted licenses in states that do not have legalized gambling, which means the only place t gamble in those states is in the Indian Casino, and they do not pay taxes on that money.
Many states are waking up and realizing that there is a very profitable business out there that they are not getting any revenue from, and not only does it bring money into the state it also creates thousands of jobs for each casino that opens. So for a state with a high unemployment rate this means more people are working and less of the stats money needs to be spent on these people, again a win for the state and the people.
It also means more money for the state to feed kids a hot meal at lunch and the money to put new books in the classrooms and maybe to build more schools. This money is also used in some states to hire more police officers.
Legalized gambling besides bringing in more money to the government in taxes also brings money into the community gamblers will use services such as hotels, restaurants and other local attractions while they are in the area. This can bring a major boost to a small starving economy separate from that of the casino.
Another reason why many states are pushing to make gambling legal is to attempt to wipe out the illegal gambling business. Many people feel that if gambling is legalized there is no reason for people to go to sleazy and dangerous back room casinos.
These type of places are becoming harder and harder for the police to find and as soon as they do find them, they will either pack up and change locations or another will just take their place. Another bad thing about illegal casinos s that there is no one monitoring to make sure the casino is not cheating their players.
In many cases police have raided illegal casinos and found that all the table and card games are rigged for the casino to win, and if this is ever discovered the casinos operators have in the past committed murder to keep their secrets, and most people fear for their lives and refuse to cooperate with the police.
Legalized gambling is monitored to make sure both the player and the house are playing an honest game.
Do not let all of this make you think that gambling has no downside. A lot of this money has to go to treatment for people, who develop gambling addictions, and most cities with a casino do usually see a rise in crime in those areas, so more police officers are not just a luxury it is a necessity.
