If I'm rich there's no need for me to gamble anymore I'd rather spend some of my money to satisfy my needs, it's a win win situation.
I agree, if rich, it is better not to play gambling. but I do not agree if only spend for necessities. you better start a business. You can open a trading site, gambling site or casino.
If you are not yet satisfied with your wealth, it is better to invest on stocks or trade stocks. But if you are already satisfied, just spend it on necessities. Do not gamble because if you lose, it will dry out your money pretty quick. You do not want to go back to poverty just because of gambling.
