A derogatory term used by either commie bastards who don't like to see rich capitalists next to other poor, starving bastards, or dirty anarchists who despise both, the authority of the state and that of the capitalists.
A capitalist pig is probably worse than a commie bastard, and is much worse than a dirty anarchist (who is in fact less dirty than the capitalist pig or commie bastard)
"The capitalist pig buys another diamond ring while children starve in Africa"
"Long live the anarchist Confederation! Long live organization without capitalist pigs or commie bastards!"
