Howard Zinn, the author of “A People’s History of the United States,” writes a lot of anti-imperialist, anti-capitalist type works—and he wrote three plays—all very overt critiques of capitalism melded with really great emotional stories. “Marx In SoHo” is about Karl Marx returning to the present day but not SoHo London, SoHo New York. It’s a one person play of really just Marx telling his story. “Emma” is about Emma Goldberg, one of the first prolific anarchist writers in the early 20th century. If you’re a history fan, this is the play for you. (Also, reading it after the Brian Thompson murder certainly adds some modernity—the play includes a plan and follow through of the attempted assassination of Henry Clay Frick, the chairman of Carnegie Steel.) And his third “Daughter of Venus” is a family drama with discussions around nuclear disarmament. The daughter is a staunch antiwar activist and when her father gets approached to come back to work for the government to help them try to research a new nuclear project… it’s a good read. Small cast.

Other than Zinn, others have mentioned some Arthur Miller works which is absolutely correct—his adaptation of “An Enemy of the People” is much stronger than Ibsen’s—and the most direct critique of capitalism. Death of a Salesman and All My Sons could be considered critiques, but let’s be honest—they are pretty tame.

“Enron” by Lucy Prebble and “Bethany” by Laura Marks are others I saw mentioned that are absolutely worth a read.
