So as you can imagine, a few people given that kind of setting are able to change their behavior at least temporarily, maybe permanently. But most people can't deal with their addiction, which is deeply driven, by just being in a brotherhood.
On a psychological approach to addiction
When people are confronted with a feeling of being trapped, of being overwhelmingly helpless, they have to do something. It isn't necessarily the "something" that actually deals with the problem ... Why addiction, though, why drink? Well, that's the "something" that they do. In psychology we call it a displacement, you could call it a substitute ...
When people can understand their addiction and what drives it, not only are they able to manage it but they can predict the next time the addictive urge will come up, because they know the kind of things that will make them feel overwhelmingly helpless. Given that forewarning, they can manage it much better.
But unlike AA, I would never claim that what I've suggested is right for everybody. But ... let's say I had nothing better to offer: It wouldn't matter — we still need to change the system as it is because we are harming 90 percent of the people.
