Before you think that I am an unquestioning disciple, I have to say that I doubt that Mr. Chomsky would agree with my ideas. Also, I don't really think I agree with his ideas. However, his analysis is, imho, indispensible. This man is intelligent, well read, accomplished, passionate, patient, persistent, independent, and a good teacher. If the world's problems can be solved with great minds, or if at the very least great minds are capable of any contribution whatsoever toward solving our problems, then it would be an incredible folly to ignore Noam Chomsky.
I would like to refer you to a particular lecture. This guy's interests are so diverse and his contributions are so impactful that it motivated this clever piece of satire by The Onion.
This lecture is basically a criticism of either the principle or the application of the idea of free markets. I have read and heard a lot of liberals critique free markets and propose policies that ignore and destroy basic market principles. Let me tell you that most of what I hear along these lines I am extremely dismissive of. However, Noam's lecture is a valid critique. The other thing I really like about this lecture, is that far from trying to claim he has the answers for everything, he spends his effort convincing you that the problems are real.
If you have some time to invest, I would recommend taking the time to really dig into this lecture. It will make you smarter just hearing his voice.
I may not agree with every idea that he hints at. (He tends not to say all his ideas outright, but presents the motivating information). But I feel strongly the things he talks about are inequivocably worth talking about. His arguments are sound and he's asking the right questions.
