Query: Had promise, squandered promise to become propaganda tract

This could have been a great book. The first 300 pages had a lot of promise... the next 300 pages were mediocre, and the last 300 pages made me wonder whether I was reading a "hard science fiction" novel or a libertarian tract. And to think there will be a bunch more of these novels? Yawn!The promise was there, but oh, how it was squandered. Don't read this book for the science fiction; read this book if you're interested in a vastly simplified near-future utopian epic with cardboard, cliche-riddled characters and "oh wouldn't it be nice" pining. Blah.
