Excellent books. Great for learning about the economy, capitalism, government, community and family. I wish these books had existed when I was growing up as a kid. When I was growing up I had many questions about the government, how were certain things made and how society worked as a whole. In school I learned about history and forms of government, but the Tuttle Twins puts these principles and ideas into perspective and in a very practical manner, easy to read and understand. These books are not only good for children, but they are great books for parents as well. It keeps the reader and the listener engaged in the lessons and teachings found in the fun stories.
