These billionaires in which I am talking about are in the parliament, the highest level of the government. They directly oversee the passing of legislation, and hold a massive degree of influence over politics, to the point where they greatly over-shadow the Proletarians in the government.
As to the question "who are they?", the list would be to big for me to put here, given how many of them there are.
This begs the question: How can a country be a Dictatorship of the Proletariat when its head of state, its leader, is himself a landlord and multi-millionaire, if not billionaire? What kind of Communist Party has its ranks filled with ultra-rich bourgeoisie, the people we were supposed to be fighting aganist?
