Learning about equity from Monopoly

In recent months, when I played Monopoly with my kids, I realized how insidious the rule is that you don't have to pay someone who doesn't notice that you landed on their property. That rule encourages dishonesty and bad sneaky behavior--and could be responsible for the downfall of western civilization. Wait, never mind, the me-first capitalist mindset preceded Monopoly. But still, we don't play with that rule so as not to encourage dishonesty--at least while they are young and impressionable.
