It's interesting you would mention all of that. You may be right about the book, however, the author is quite different. I implore you to do a bit of googling on him and watch both of his TED speeches, just to get a better idea of him. I am not at all discrediting your review, just letting you know that the author is about a bit more than targeting "elitists" as an audience.
You may find that you become inspired once you watch the speeches, which is why many people bought this book, including myself (just haven't read it yet!).
It's my belief that you must make your own difference, no one can make it for you. If you bought a book to help you make difference, then you are likely looking in the wrong place. Everyone gets there through their own methods however, so who am I to say a book isn't one of them? heh.
good review, unbiased by the speeches (I think). I Still bought the book though, author's is too good at speeches!
