Huh. Gambling only becomes a threat to people who doesn't know the word 'control.' For the most part, gbling is usually harmless and brings a lot of fun and brings a lot of money to the table and jobs for people. The addicted ones made themselves a slave to gambling and to money, that's why they can't seem to get out of it. Saying gambling is a threat to gamblers is like saying scuba gear is a threat to scuba divers which literally makes no sense. Without gambling, there wouldn't even be gamblers in the first place!

It's a psychological thing really, and depends much on the capability of the person to resist temptation to gamble hard and lose money in the process, nothing to do eith gambling simply existing in the economy.
