An element of chance is fine, if it allows interesting decision making. Good games of chance indeed involve strategies like hedging your bets. But with Monopoly, 90% of turns involve literally no decision-making - you roll, move along, and pay out or not. Occasionally you have a tough call to make about whether to buy a property, or how many houses to buy - but those are the exception rather than the rule. 90% of the game is essentially you doing bookkeeping for the game.
