I agree, thinking about my post again it is much weaker and not really useful to the discussion.

Although I did have the purpose of conflicting with some fictional evidence; for example, vampires always turn out to be rich and in "Deepness in the Sky" Pham Nuwen is said to have built up a trillion dollar fortune out of nothing after abandoned on a planet. These sorts of things tend to imply that regardless of the circumstances of a person if they are smart enough they can work their way out.

It's somewhat distinct in that the fictional characters have a basis to build upon whereas a newborn does not, but if anyone is updating on fictional evidence they should stop.
