It's unfortunate to see so many people who haven't purchased the books, read them, or even glanced at the website would come here and leave 1-star reviews because they don't agree with the views of the author. If you hate freedom, love the government taking your rights away, and want to live in Socialist State where you own nothing and are happy, then these are not the books for you.
However, if you are a patriotic, freedom-loving American and want your children to understand vital concepts regarding the true workings of the government and economy then I would encourage you to pick up the set and read them as a family. I'm sure the adults will learn something too.
We own the set and read them and love them.
