I could, if I were so willing, even make a more elaborate case that the three greatest silent-comics represent three major American political strains.

Lloyd, always playing the college student, white-collar worker, ordinary middle-class guy, is the Right/Conservative American.

Chaplin, as “The Tramp” is often the perpetual, unemployed victim. Fitting quite well into Chaplin’s own Left/Socialist/Communist world view.

Keaton, who’s politics I’m unfamiliar with; always portrayed the honest, hard working ordinary blue-collar guy, who no matter what things befall him, never sees himself as a victim, but just carry’s on and often wins in the end. Similar to the majority of moderate, apolitical, middle-America.

Another thought: Chaplin’s (Lefty/Socialist) movies are now the most oppressively preachy and self-important. Make of that what you will.
