Well, the farm was supposedly "communist", so therefore, the animals would have been reward with food and other resources but instead, they weren't really rewarded.. the pigs were the ones who were rewarded rather than the other animals.
and instead of rewarding them, they even send boxer (the hard-working horse) off to the butchers to be fed to dogs in order to obtain some alcohol.
It makes sense; but there are two phrases there that could be divided to make the sentence flow better. “I am not happy with myself, nor will I ever be.”
