The New York Times features a charming op-ed about playing PROPER Monopoly at the University of Chicago during Milton Friedman's tenure:
Monopoly was taken seriously in Shorey House at the University of Chicago in the late 1970s. A room was set aside as “The Monopoly Room.” But in that post-Vietnam, pre-Reagan era, all assumptions were questioned and a game our parents played was no exception. Rules were meant to be altered. The house even convened a “constitution convention” to change the official rules of the game to allow a person to build a hotel on a property without first having to own four houses. Mr. Zelenty, now a corporate lawyer in his native New Jersey, remembers holding a sign that said, “New Jersey Espouses / Hotels Without Houses.”
The other thing taken as seriously in that dorm was free-market economics or, more precisely, Milton Friedman, the University of Chicago economics professor. This was a house that frequently invited Professor Friedman and his wife, Rose, to sherry hours. House members ran a snack bar in the basement of the dormitory called Tanstafl, an abbreviation of a saying favored by Mr. Friedman, that “there ain’t no such thing as a free lunch.”
Mr. Zelenty owned the greatest of treasures any of us could imagine because it combined those two passions. He had asked Mr. Friedman to sign his Monopoly board at one of those sherry hours. The Nobel laureate did so, writing, “Down with” above the game’s name. We didn’t play on that board. No one ever played on that board. (Mr. Zelenty said he still has it and wants to donate the relic to the university one day. “It’s in a place of safety more than a place of honor,” he said.)
The conclusion of the game? After allowing the bank to print money to cover expanded asset purchases, the players were immediately faced with extreme inflation. To counter this, the bank moved to take money out of circulation leading to a profound depression.
