I was so young when I read this I had trouble understanding it (I'd read Animal Farm). This is one of those books everyone should read, especially now. I went up from 4 (readablity) to 5 based on this book's place in the world, what it says and what it warns.
I still highly recommend this book...I'd also recommend Brave New World
as that book seems to be more the way we're heading at this point in history. Still If you've read Soft Despotism, Democracy's Drift: Montesquieu, Rousseau, Tocqueville, and the Modern Prospect
you'll see the way things tend to head historically.
Still highly recommended.
