to understand the new economy i propose the following twist to monopoly:
play monopoly according to all standard rules, you only change your behaviour, viz all players share their money.
So there are two piles of money in the game: one for the bank and one for the players. When a player passes go his income is moved form the bank to the players pile and when a player receives money from another player this is also deposited in the players pile. When a player wants to buy real estate or has to pay rent he takes money from the pile to pay the bank resp his fellow player
One variant of this setup is to start playing the conventional way and after some time, eg when the first bankruptcy occurs, switch to the new behaviour.
