I think politics is deadly to write about, frankly. If you have a political agenda and you set out to write a novel to prove that, say, capitalism should crumble, then it's going to be a really bad novel. Very few people have been able to deal with political fiction - Dickens, Dostoyevsky. But even Tolstoy got really tiresome when he was talking about the serfs. You have to let characters be characters, not [gruff voice] Mr Capitalism or [girlie voice] Miss Anti-Fur.
