The game of Monopoly was created to promote common ownership of land.
When the game Monopoly was first patented in 1904 it was quite different than the game we know today. "Called 'The Landlord’s Game,' it was like the version you grew up playing, in that it could be won by accruing as many land lots, properties, and cash as possible. But her (developer Elizabeth Magie) version came with a twist. At any time, the players could choose a more egalitarian future by voting in the Single Tax rules.
“Magie admired the radical philosopher Henry George, and hoped the Single Tax rules would educate players of all ages about his proposal for common land ownership. These calls for bold reforms emerged from anxieties of the first Gilded Age. Magie and George had lived through an era marked by rapid economic growth, deep inequality, political corruption, and sprawling industry trusts controlled by a few men. The status quo seemed unsustainable." Mmm. That sounds familiar.
