How could animal farm represent economic and social systems?

The first chapter of Animal Farm can represent economic and social systems in many ways because it has lots of references to the economic and social systems. It states that the farmer chouses every thing for the animals in the farm. This tells me he represents a dictator because he bullies and forces the animals to do things so he can get his way. Also Major’s speech was about how all the animals should be united and over throw the farmer. This reminds me of communism. It reminds me of communism because it shows that every one should be equal in their rights even the rats. This also fallows Carl Marks theory were it goes form a monarchy to a free trade system to a dictatorship and then to a communist economical set up. So far there has been lots of references to economical and social systems so far and we are only in the first chapter.
