Axiomatic

Gambling is a kind of tax: a tax on stupidity. A tax on greed. Some money changes hands at random, but the net cash flow always goes one way - to the Government, to the casino operators, to the bookies, to the crime syndicates. If you ever do win, you won't have won against them. They'll still be getting their share. You'll have won against all the penniless losers, that's all.

Nobody wants to spend eternity alone.
