Is "good enough" really good enough?

I have some questions on good enough parenting. First off it seems that Dr.Sandra Scarr searcher only includes middle class families.We talked about how poverty can effect people but it seems odd that Dr. Scarr would only focus on the middle class. Is it really "good enough" parenting or does it have more to do with their socioeconomic status? Also does a parent always have to be "good enough"? What would the effect be on a child if their parents were both alcoholics form the time the child 2 until they were 4 but both sought help and are now good enough parents.

I briefly read over Dr. Scarr's article she published about parenting styles. The article seems to talk a lot about IQ but not so much about behaviors and personality. It does not seem to have crime statistics on children of "good enough" parents. I would believe that "good enough" parenting compared to super parents does not have an effect on IQ, but parenting is much more then IQ.

I do think that being an active an engaged parent is important. No your kid doesn't need every new toy that come out. Kids need parents that care and are emotionally available to them. If that what Scarr believes is a good enough parent then I am with her. I think the idea of being able to be "good enough" take a lot of stress off of parents and allows them to make mistakes. I
