@Foxfyre,
Foxfyre, I want to say that I hear you in regard to troubled childhoods, no childhood is perfect, and as you say, children can and do reverse what happens to them in childhood, good or bad, but the odds are better if you have a good childhood. By the way, I do not include affluence as an indicator, or wealth. I am mostly talking about having a loving family and whether or not a child is rejected by parents. Other factors for dictators also have to intersect with this, such as a big vector of politics, charisma, etc., it is a host of factors.
We all relate it to our own experience, but honestly my parents were not rich, but we worked hard, and we had a loving family, with no rejection. Of all the kids I went to school with, more than 90% could say the same thing I am pretty sure. I went to a small school and most of them I knew very well, along with their families. Some of the parents, my parents dealt with in regard to farming, helping each other, working for each other, etc. Most wer all great people, no axes to grind, they all loved America, every one of them.
