Alcoholics Anonymous helps people admit they have a problem. In most cases people don't want to admit they have a problem with alcohol. Being in this kind of program helps the individual(s) take steps to deal with their addiction. These kinds of programs also provide people with support groups. In most cases the support groups have other individuals with the same problem, these people understand what everyone is going through and they don't judge others.
