I dont doubt that scientists who have studied alcoholism have done extensive research but there's always the danger that people who have any form of addiction will blame their genetics or society for their problems. It's the same with those who blame crime on poverty ignoring the fact that not all lawbreakers were born poor and not all poorer people commit crime. From personal experience of having seen alcoholism in my family when growing up, I would say that children of alcoholics would probably take more care to avoid the same path. I drink occasionally but have it under control.
