True. That is indeed very interesting. Although not limited to comic books. You can spot a similar pattern in movies too. Somehow, in America, the films to become the most popular (or most successful) mostly featured themes portraying powerful people in a positive light, directly or indirectly. While in Europe this trend never really took root.

In a classic, underdeveloped autocracy, the answer would surely be blatant censorship and prosecution of authors portraying different views. However, the American mechanisms for accomplishing the same goals are considerably more complex and intricate. That is, assuming there was or still is such a mechanism, as I’m not sure we can say that definitely. Perhaps it was all just a natural process of people preferring the easier, more convenient narratives?
