Highly recommend these books, I have the whole set. In this age when people think that the government is the answer to all our problems, when socialism "sounds nice" but actually wreaks havoc, we need to continue to teach our children the importance of free markets, small government, entrepreneurship, etc. I am not am extreme libertarian, and may not agree 100% with all libertarian views but I definitely appreciate what me and my kids are learning from these books and that we are able to have some good discussions and balance out the left-wing perspectives that seem so common these days. Plus they're just good fun books to read with kids!
