To eviscerate anything implies to disembowel or deprive it of something necessary for living. The proletariat can refer to either the working class (as in Marxism) or the lowest social stratum in Roman society. In this context, it meant that the elite would take everything they could get their hands on, including their clothes, their money, and even their lives. The English word "eviscerate" comes from the Latin verb exsudare which means "to draw out". Thus, it means "to draw out (something unpleasant)". "Eviscerate the proletariat" is like saying "disembowel the working class". It means to destroy everything that makes them unique or valuable. This action would leave nothing behind except for some blood and guts on the floor. In conclusion, the elite would destroy the working class by taking everything they had worked for over the years. They would then be left with nothing except for some blood and guts on the floor.
