&quot;The biggest problem I see with gambling is that the Pareto effect shows an ugly face there: often it&#x27;s just economically feasible for the operator because of the addicts.&quot;<p>I&#x27;m addicted to Hackernews.  Does the fact that it&#x27;s a free site make the operator any less responsible?<p>How about we just make everyone personally responsible for their own actions.  Gambling addicts can just block the website.<p>Bartenders have a responsibility not because of addiction, but because someone could actually kill themselves or others when they are too drunk.<p>I also don&#x27;t see the medical marijuana dispensaries responsibly for people that ruin their lives due to MJ addiction (yes, I know that it&#x27;s not chemically addictive, but like gambling, you can get addicted to it).
