The key innovation of her game, however, lay in the two sets of rules that she wrote for playing it.
Under the ‘Prosperity’ set of rules, every player gained each time someone acquired a new property (designed to reflect George’s policy of taxing the value of land), and the game was won (by all!) when the player who had started out with the least money had doubled it. Under the ‘Monopolist’ set of rules, in contrast, players got ahead by acquiring properties and collecting rent from all those who were unfortunate enough to land there – and whoever managed to bankrupt the rest emerged as the sole winner (sound a little familiar?)
The inspiration began with a book that her father, the anti-monopolist politician James Magie, had handed to her. In the pages of Henry George’s classic, Progress and Poverty (1879), she encountered his conviction that ‘the equal right of all men to use the land is as clear as their equal right to breathe the air – it is a right proclaimed by the fact of their existence’.
The original inventor, Elizabeth Magie, sounds pretty cool.
