There are excerpts of the book at that site. Chapter 6 on the deliberately forgotten history of free trade is interesting.
I read it. I have also read Adam Smith, Henry Hazlitt, Ludwig von Mises, Frederic Bastiat, Milton Friedman, John Maynard Keynes(tried to, anyway, his writing does not hang together and is logically nonsense, apart from the economic arguments he seems to be trying to make which are also nonsense), Ricardo, etc.
When England went to a regime of Free Trade in the 19th century England prospered as never before or since.
