It was originally fraught with political and economic references, before Parker Brothers sanitized it in 1935. For example, the reason for the "go to jail" square was that you had trespassed on a rich man's estate. Now that I think about it, there were other "economic" games when I was growing up, back in the dark ages. One was called "Pit," named after the "pit" of the Chicago Commodity Exchange. The object of the game was to corner the market in wheat, corn, or some other commodity before any one else in the game. John C. Medaille
