I actually think money can make me happy at this point. You're right about poverty and not being able to provide cover in times of stress; It does something to you. I certainly have experienced it first hand.
Just seeing excerpts from the book you're referencing seems a bit harsh, but then again, so is the true face of reality. Think I'll pencil it down on my 'To-read' list.
It does seem harsh, doesn't it? But there is supposedly data to back it up. We are all limited, but under stress, we become more so.
