I would say that Boxer probably best represents Orwell's point of view. I think that this is something that is brought out for a variety of reasons. The first is that Orwell's story ends on such a cynical note in that freedom and autonomy are not recognized through the government. Collective happiness is not something that is seen through Napoleon's reign. In the end, when the other animals cannot recognize the difference between the humans and the pigs, it helps to bring out the fact that there is an overwhelming lack of faith in the governmental structure. With this in mind, I would say that Boxer becomes the ultimate representation of how Orwell views individuals and their relationship with government. Boxer has blind faith in the authority structure. Never questioning any of its ulterior motives and never raising any voice of dissent, Boxer continues to "work harder" and do more. In the end, after giving everything he has to the machine of government, he is crushed by the weight of that machine and conveniently "forgotten" so that others can continue to become the grist for government. This sad and cynical read is something that Orwell, himself, believed in towards the end of his life and in the belief that human freedom and expression was not being properly channelled in both the Communist world and the supposed "liberalized" West.
