Yes, what you say about people raised in loving environments being more vulnerable to optimism rings true for me. My parents had it all sewn up, as did my aunts and uncles and everybody I knew. I had no reason to think that life wouldn't be perfect. I didn't see anybody peddling furiously behind the scenes. I basically stepped out of one failed life and went back to the drawing board in my mid-thirties. With just the clothes I stood up in and a new attitude. From now on, I was going to have to stop passively hoping for the best, and put some effort in, draw some lines in the sand, make some tough choices. I am happy now with the life I created for myself, and I think I knew I could do it (although I don't know if I felt optimism in a time in my life when I had nothing) but I know I stopped blithely assuming that everything would la la la la la fall in to place. I have some things, I don't have other things, but the things I have, I value them so much now. It turns out, life doesn't just reward you for showing up. I am not unhappy but I think I only started to build the security I craved when I lost that default optimism that my privileged family background gave me. I hope I have understood your article correctly. I know how frustrating it is when somebody seems to miss the main point.
