In chapter 10, what message is Orwell communicating when he has the new commandment added?"All animals are equal, but some are more equal than...

In the end, I think that the last commandment is a
paraphrase of how power is a cyclical element.  To quote The Who, "Meet the new boss-
same as the old boss."  The last commandment brings to light how very little has changed
on the farm.  The tenets of animalism have been completely undermined, Old Major's
vision totally discarded, and the power structure has returned to a "top down"
configuration of government.  Orwell's vision of government has come full circle.  The
consolidation of power that the pigs desired has made Manor Farm one in which the
animals lack power and lack control over their lives.  The last commandment brings this
into clarity in that there is no such thing as equality and as long as the animals lack
the competency or will to voice discontent, there will be a complete resumption of power
that Jones held over the animals.  Life has not changed for them, as their suffering has
continued.  Animalism has become another tool to keep them in check, eliminating their
power and silencing their voice.  In the end, the last commandment brings out Orwell's
belief that political structures in the modern setting seeks only to substantiate their
own sense of being and control.  There is little to indicate that such structures will
be empathetic to citizens unless they hold their governments
accountable.
