Bought this book at the same time as I bought 'Whoops' by the same author. Whoops was a great piece of research into the banking crises and what went wrong with the financial system. Capital is the book that the research was done for. I was expecting something fantastic, a real state of the nation novel with a strong central story in the 'we want what you have' campaign. Sadly for me, it didn't really deliver. It starts very well, but the longer it goes on, the more you realise the separate stories aren't ever going to connect, and 'we want what you have' is more like a half finished idea, tacked on to the book to artificially link the stories together and never really going anywhere as a central story.
At over 550 pages, it's too easy to lose interest in the various stories. They're all okay, but there's too many of them, and accurate as they all are, it needs something more to be the great book it's made out to be. Read Jonathan Coe's What a Carve Up if you want a real example of a sprawling state of the nation story that works.
