Studying history can help us understand the consequences of price control and utopian policies, and how they can lead to disastrous results.

• Studying history makes you realize how long people have been doing the same foolish things with the same disastrous results.
• Price control can have devastating consequences, as seen in the aftermath of World War II.
• Price control can lead to unintended consequences, as seen in international naval agreements limiting the size of battleships.
• Utopian feel-good policies led to even worse horrors in the second world war.
