Everybody knows how casinos work and the inevitable results of patronizing them too frequently or enthusiastically.
So why are these people, like the drug addicts they are compared to here, doing something that they know is not good for them? We've read some of the reasons, lonely, bored, feeling useless or abandoned, and so on.
We are a profoundly unhappy people. Hardly any of us wouldn't rather be doing something else. "Life isn't fair", "Why do you think they call it work?" Is there anybody that hasn't heard these and similar admonitions their whole lives? Why are you spending your all too short life doing something you'd rather not? How do you think you will feel 40 years from now as you look back and realize that you've lived your life without doing the things you really wanted to and now it's too late? Or maybe that you sacrificed what you were doing in order to "raise a family" only to now have that family look on you as a burden or to feel that way about yourself?
Yes gambling is a problem, but it's mostly a symptom of living in a world not of your own making, where you are forced into spending your only life working to achieve somebody else's dream and in the end they aren't even grateful.
