Before I even opened this thread I was going to recommend some Bill Bryson because I'm currently reading Notes from a Big Country and utterly adored Notes from a Small Island, so I very much second the suggestion that you read some Bill Bryson.
I don't see how he's unfairly cynical. He can be but usually only for good reason. I think he starts one of his columns by describing how his wife just thinks he bitches all the time in his column, but I find his enthusiasm for little things like garbage disposals or junk food to be terribly endearing and that he displays a rather great enthusiasm for both Britain and America.
Otherwise, along the dystopian themes, try A Clockwork Orange or The Man in the High Castle.
