The origin of this term for the underclass is less clear, though it may refer to the fact that the Revenus acts as a cheap source of labor and certain other resources for the Logos (in French, the word Revenus can mean "income", or alternatively "return on investment". It can also directly refer to a government's income, monetary or otherwise, from taxes and other levies. The most common meaning of the term in modern French is "finance' though this is clearly not the implication of the term as it is used here). See also the derived English word revenue.
