Animal Farm. How isn't that about government, in general?

[The Backlash Cometh]

I know the theme of Animal Farm was about communism, and how leaders eventually evolve into the very people who exploit the working class. Well, I know that now, but when I first read it, I thought it applied to Capitalism. The theme: that anyone who steps up to represent you, eventually morphs into someone who chattels your welfare in order to improve their own standard of living.

Am I the only one who picked up on the polarity of the theme?
