I first heard about Noam Chomsky when Jello Biafra made a reference to him on one of his spoken-word albums, which led me to pick up "Understanding Power." I must say, this book is a harrowing retrospective of all the rotten things America has done since the early 20th century, and basically what can be done to prevent a future that rests in the hands of all-controlling corporations. It goes without saying that Chomsky's glasses are anything BUT rose-colored, but his points are valid and honest--if you can't deal with what he's saying, the evening news is waiting for you.
