The "Declinism" of the Anglo-sphere

I'm reading a book right now, that points out how futile it is to make predictions about the future. If you liked Malcolm Gladwell's books (The Tipping Point etc.) you might like Future Babble - Why Expert Predictions Fail and Why We Believe Them Anyway  by Dan Gardner. Its easy to read, filled with interesting historical tidbits, and offers reams of examples where brilliant people made predictions that had no relation to what actually happened. Predicting the future is a mug's game, rarely will the experts be held to account - people forget.
So when I read Mark Steyn's Dependence Day, On the erosion of personal liberty, (thanks Jeffery), it did not take long to see that Mr. Steyn was predicting the demise of the Anglo-American classical liberal democracy that has dominated the world since the rise of the British Empire.
Mark Steyn's article is long, extremely well written and very distressing if he is indeed right. I'm leaning on Dan Gardner's view that Steyn's predictions will be wrong, no matter how well argued they are. Here's hoping!
