Mrs. Warren's Profession; by George Bernard Shaw.

Age old dilemma of society - "respectable"vs. the other side, and the need of one for the other. It must have of course been extremely controversial when it was written - and published - but this writer was always more than equal to any criticism and could always argue either side of a debate with reason.

This one is not a comedy, though, and one is presented with Mrs. Warren's side quite reasonably.
