I’m not so sure what that play would be. Perhaps you might want to read the article by Thomas Lifson that the author linked up to. Miller was a rotten skunk and his work was consistently anti-American.
I was a drama major in college. Of course we all had to study the "great playwrights"; and many of our acting and directing scenes were culled from plays by Miller, O'Neill, Tennessee Williams, Shaw, et al. Looking back, almost all the plays were nothing more than screeds against the American Dream; or were pro-homosexual and pro-communist, etc.
