A not-so-well-known fact, thanks for publicising. The Women's History website has a lengthy entry on Elizabeth Magie and her "Landlord" game with the Prosperity and Monopoly rule sets.
Magie, in 1903, "actually designed the game as a protest against the big monopolists of her time—people like Andrew Carnegie and John D. Rockefeller."

@albertcardona @Heliograph I think it's also helpful to remember the context of the time - board games were thought of in USA/UK as being basically for children, and were often expected to have an educational side (e.g. snakes and ladders boards showing virtuous and non-virtuous behaviour). As distinct from card or dice games, which were for grown-ups to lose fortunes on. 😀
