First remember that Monopoly is awfully socialist. You're NOT leveraging capital but operating on a basic level of fairness. To make it a little more capitalist we make a variety of stacks of very different amounts of money and pass those out randomly for the start.

Secondly to better resemble capitalism you would need to give each player a different role, rules and an entirely different goal. Games where everyone is doing something different tend to not be not much fun.
