It's a very fun, humorous and light-hearted introduction to Marxism and what it really means in today's world.
I must say it is one of those books that ends faster then you expect it too and it also gives you a lot of pointers to other books, movies and cultural references, should you wish to go further.
So, if like me, you didn't really understand much about socialism, communism, Marxism and all the different flavours of left-wing ideas, it is a great book to start and also have a laugh while you are at it.
It is a bit America-centered, but that is what you get with American authors. It's not bad though, he is pretty self aware and doesn't ride a high horse.
