Unfortunately, being more aware than - and immune to being fooled than - the majority of a specific voting bloc is not a historical anomaly. Take, for example, the Jews who were privileged and fortunate enough to have the foresight to flee Europe during the rise of Nazism. They saw the writing on the wall, and were wise to the foolishness and depravity that was on the horizon.
Most populist movements are very much the case of “they’re all too stupid to know they’re being fooled, unlike me” - although I wouldn’t necessarily use the word “stupid” and I wouldn’t necessarily limit it to “me”.
