Angels in America is definitely a play with a point of view. In case you weren't paying attention (for like the whole play), Prior sums it up for you in his final monologue, telling us that "The world only spins forward" (Epilogue.31). The play argues that humans, by our very nature, need to progress and change – it's just who we are. But what exactly is humankind progressing toward? In the play's view, the goals seem to be social justice, a more equitable distribution of wealth, and environmental sensitivity. What do you think? Is this your idea of progress?
Angels in America argues that progress is not only necessary for mankind – it's inevitable.
In Perestroika we see the theme of progress on a personal, societal, and cosmic level.
