I understand the moral feeling that you're earning money off other's losses, however, I see it a bit differently. Gambling is,....like many other things in life,...a form of entertainment for most people. Super Bowl tickets run 600.00 to over 1000.00 each, and that's before you rent a room, buy an 8 dollar beer or two, etc.! lol You leave with a feeling of having a good time, but that's it, and the money is gone.
Gambling is fun, and auxilerating at times! You even have a chance to have the experience, and maybe even walk away with what you started with, or more. To me, it's all about how an individual choses to spend their entertainment dollars.
Where I would feel a little bad is if someone is losing more than they should, or can honestly afford to lose. It happens, however, this happens in other areas too. I've see people all the time spending money on crap they don't need, and can't really afford! A couple of them work for me! lol
I had to ask one of my guys,...do you really need TWO 64 inch HD TV'S right now?? Yep, he had one, and put another one on a credit card. He's single BTW, and lives alone! lmao! So he struggled, and ate Hot Dogs and Beans for two months while he pays it off!

It's a personal choice.
So some of this is just being responsible. We can't be responsible for player decisions. The moral issue is on them, not us. JMO, so don't feel to guilty Fiction!!
