To those with interest on this topic, I would recommend "Losing Big: America's Reckless Bet On Sports Gambling" by Jonathan Cohen.  The genie is out of the bottle thanks largely to state governments who were for the most part running at deficits and saw gambling tax revenue as "found money" which it desperately needed.  I worry for my kids' generation in general where it's never been easier to place bets and so many will end up being in denial of a gambling addiction which is a very real thing.  Making things absurdly worse are the MGM's and Draft Kings of this world who can identify poor gamblers willing to risk high stakes and do everything short of coercing these individuals to place bets (offering many perks as an inducement for doing so).  I predict that within the next 5-20 years, this is going to be a huge societal problem.  Athletes getting in on the act?  Not the least bit surprising, quite sadly.
