Your revisionism is pretty glaring to anyone who was paying attention during the mid-1960s, as I was — my USAF dad was stationed in east Texas then, which was more deep South than Old West.
Let's just say we have very different takes on what can motivate humans, individually and in groups. At the risk of sounding condescending: I used to feel somewhat the way you seem to. My naively-rationalist and very-judgmental views evolved as the years went on. The evolution was driven largely by life experience, which drove home the brute facts of human inadequacy, irrationality, and just plain fuck-ups — principally my own, along with those of friends and loved ones — along with the pervasive role of random chance. It took quite a while to figure out how my rationalist, judgmental worldview could accommodate those brute facts (spoiler: it couldn't).
