Widowers' Houses; by George Bernard Shaw.

In a way this play is a companion os Mrs. Warren's Profession, both about money earned by a parent through unsavoury means of varying questionable repute, of course this one being far more common than the other both in practice and held not so often repugnant by society - rich society that is - but morally no less, in fact in some ways more, reprehensible.

Mrs. Warren's profession is held in n good repute anywhere in the world, but it can be argued that most people in that profession are not in it from choice as much as from either being kidnapped and brought into it or from necessities of survival of a family which often when needed to be provided by a woman she might find little or almost no recourse. When one is safe, moralising about another's circumstance is all very well; it is likely to be another story when it is your own child's survival in question and you have not much of a choice.

This one is about rich people who earn their living by providing housing bordering on slum to the poor and then charging extortion level rents while providing little or no amenitites, and evicting those that default at short notice without care about if they could in fact survive.

And yet most rich could hardly stand a scrutiny about the roots of their wealth - if it is not opium or colonial (robbery) it might be soemthing akin to this, or worse - it might be selling things that actually damage those that pay for them. Not just illegal substances, either - often legal substances can be just as bad for health, even lethal, and yet they take time to become known as dangerous or worthless at best. Even today that is true of much that forms multi billion industries, in much misused names of fun or beauty.
