I won't say a lot, but I'll say this:
Some years back; I don't remember why I bought the book (I must have been on the recommendation of a friend), and it stood unread on my shelf for some time, before i finally picked it up. The title was provoking, as I was still a firm believer in democracy before I read it, but when I finally turned the first pages, I got hooked - it was like new doors of knowledge were opening up for me, and it was disconcerting, because (as many others who read this book can attest to, I'm sure), the message of the book broke down the political illusions we create for ourselves. And the more I read, the more I realized that a blind faith in democracy today is just as bad as outright supporting tyranny.
H.H. Hoppe convincingly shows how the rise of democracy (publically "owned" government, as opposed to privately owned government, such as monarchies) around the start of the 20th century has resulted in a massive success for socialism (and thus erosion of private property rights), and a dire failure of sound financial and monetary policies. And, of course, the eternal growth of the state, which is now invading more and more of our personal lives and taking away our economic freedoms.
You should not read this if you are reluctant to have your political opinions challenged. Read it enough, and you may become an anarchist - consider yourself warned!
