You are right. It is simple only in so far as it is simple to state. It does require of the populace a lifetime of exertion of effort. It is certainly sustainable by most of the population in principle, we know that from history and from situations of deprivation where existential or other dangers forced populations to exert that effort in order to avoid danger. Civilization itself is the act of removing such dangers, and when they are removed, the society often then begins abandoning the exertion of effort as it provides no real benefit to larger and larger numbers of the population. Unfortunately this eventually results in the population being unwilling to sustain or expand the infrastructure that protects them. As far as I can tell, this is the largest problem that faces the human species as a whole. Civilization brings about its own undoing. Emotion and rational thinking are not opposites. I am aware of the neurological cases you're likely referencing, and think that they are extremely important to understanding the interplay of emotion and reason. Without emotion, it is impossible for people to make decisions regardless of the amount of information or understanding available about a situation. Even with a list a mile long of "pro"s set next to a list with only a single "con", a person without emotion can not make the decision to act. It is indeed debilitating. Emotion certainly doesn't need to be eliminated or anything of the sort. It doesn't have to be misleading, it simply can't be relied upon in the absence of reason. Emotions are a basic trained response, and inexplicably linked to the physiological processes of their manifestation. They would probably be extremely useful if we lived in an illiterate possibly pre-lingual tribe on the savannah in Africa where they evolved as an important tool. Our world is far different from that, though, and so we have some baggage we have to deal with. As far as I'm aware, critical thinking is the only tool we've got to recognize and deal with that baggage intentionally.
