>How would you explain to someone who is not American (and never been or lived here) - in 2 or 4 sentences - the connection between Native Americans and Casinos? That is, how the Native American Gaming has been established and being regulated? and how native americans benefit from the casinos?
>TIA

Actually, googling "Native Americans and casinos will bring up a nice selection of articles on the subject. Wikipedia, http://en.wikipedia.org/wiki/Native_American_gaming, here's another on the history: http://www.santaynezchumash.org/gaming_history.html

Basically, Native American Gaming is regulated by the Congress at the Federal level and very few have actually benefitted from it.
