Having worked in casinos for 20 years, my outlook on this will probably be a little different...as they say in the business, it takes about five years to really learn the business....spotting cheaters, handling people, etc..all on top of the technical stuff that goes with each game.... for a while it's fun, then it's just another job, and then one day you start thinking it's no better than dope dealers...
Gamblers may start out "recreationally" but any casino has its regulars, and once they "get the habit", that's it...every spare waking momnet, and dime, goes to gambling...and then it's not just spare dimes but rent money, milk money, etc....
The casinos are in the ego business as much as whatever business they want to call themselves, "gaming", entertainment, recreation, etc...They cater to people's egos and let those people blow an awful lot of money, each thinking they'll be the one to overcome the odds....
- Early on in America, when a lot of people were illiterate, a banner with a tiger on it hung in casinos, it meant "come try to beat the tiger ( the odds) - that tell you anything?
In the 80's, the Vegas casino owners for the first time had to go to out -of-state bankers to finance their new construction projects and expansions. In the west, that meant Salt Lake City... that meant Mormons (Mormons own casinos, they don't encourage their own members gambling in casinos).... so, they had to come up with an acceptable term for gambling as gambling wouldn;t get a lot of finanacing approved, and that's when the industry fell in love with the term "gaming".
It's like this folks, walk in and bet your money, you are gambling, the casinos are the ones in the gaming business.
Gamblers biggest enemies are themselves. Casinos keep growing and growing because a person with $50 "to blow" will lose an additional $350 or much more trying to get the original $50 "back". People who want or will want their losses back have absolutely no business at all walking in to a casino. The only way anyone can gamble successfully is to consider the money already gone once it's converted to "chips" ( misnomer, actually cheques) and anything that comes back as gravy. Only one in a thousand play that way.
As far as the OP, Playing Poker a Sin or not? that one is very tough- there was a court case in Califronia years ago to decide if poker was gambling or skill. The court decided poker was a game of skill, because over the course of several hours, the players would all get an equal amount of good and bad hands, it's how they played those hands that determined who won.
As for gambling in general, coinsider Proverbs 26:11
As a dog returns to its vomit, a fool returns to his folly
