Michael Medved had on one of the authors of The Natural Family. That author made clear that he felt that it was vitally important for children to be raised with their natual biological parents and that any non-nuclear family does irreparable harm to the child. There are a few problems with this. The first is that this supposed natural family has never existed in history. Even in the past when children weren’t born out of wedlock as frequently (or at least it wasn’t known about, which might be equivalent) you still had a large percentage of children who were raised by a stepmother and not their natural parents. So to claim that our nuclear family is natural is far-fetched given history. (I mean is there any reason to believe that in primitive societies father’s contributed anything towards raising their children aside from protection and food) The other problem is that if he is right you would expect there to be a Golden Age in America approximately 20 years after the families were all so wonderful. In fact the 1970s are considered one of the bad decades yet these children were raised in the glory filled 50s. The children of the 50s were born in 20s and 30s families which lacked the moral fiber and the strong father figure. So in other words until there is some extremely strong evidence I think a natural family is pretty worthless.
