Arthur Miller was a liberal who abhorred inequalities of labor and race. For his liberalism, his criticism of what he perceived to be the inadequacies of American society and perhaps also for his Jewish faith, Miller developed a reputation as a communist.
Miller's career overlapped with the McCarthy era. Miller openly opposed McCarthyism and anti-communist witch hunts and associated with many of the organizations and personalities that Senator Joseph McCarthy's House Committee on Un-American Activities pursued.
Miller never self-identified as a communist, but he espoused many typical communist sentiments during his life, both in his work and his interviews. In an 1946 interview with the communist newspaper The Daily Worker, he suggested that the most important post-World War II work entailed raising the living standards of people around the world, and he labeled imperialism as the enemy.
