I think most people are in this situation in life, but would disagree with you. The game itself was intended as an educational tool to illustrate the negative aspects of concentrating land in private monopolies, hard to get the message when it's over quickly.

Yes, this design was intentional. Moreover, Monopoly as we know it today was intended to be one of two rulesets, the sucky one.

The good one was intended to demonstrate a better alternative.
