I am a CPA. As I prepare income tax returns I see the W-Gs from people who have won over $600 in a casino. I almost never see less in losses than the winnings. It depresses me that people waste their money that way.
I gamble a little. For example, when Powerball is over $700 million or so, I sometimes remember to buy a ticket. After all, you definitely will not win if you don't buy one. But that is it, one ticket. I have gambled at the casinos in Las Vegas and Laughlin playing craps. When I go completely out of control wild I have lost as much as $40 over the course of an evening of entertainment and free drinks. I have also come out ahead a few dollars on rare occasions. With the higher minimum bets these days, it has lost its allure. If you are losing hundreds of dollars or even thousands, it stops being entertainment.
