Scott McLemee has a great interview with Jeet Heer, on the original Little Orphan Annie:
In 1931, Daddy Warbucks loses his fortune to unscrupulous Wall Street speculators, is blinded, and lives for a time as a street beggar. But after hitting bottom he regains his fighting spirit and outwits the Wall Street sharks who brought him and America low. By 1932, the villains in the strip are increasingly identified with the political left: snide bohemian intellectuals who mock traditional values, upper-crust class traitors who give money to communists, officious bureaucrats who hamper big business, corrupt labour union leaders who sabotage industry, demagogic politicians who stir up class envy in order to win elections, and busybody social workers who won’t let a poor orphan girl work for a living because of their silly child labor laws. Gray started to identify liberalism with elitism, a potent bit of political framing which continues to shape political discourse in American today.
