"The Party is a system of organizations and obviously has its necessities. The formation of an army that is numerically much larger, more vast, also has its necessities. Marxism, and especially Chairman Mao, has taught us how to resolve this problem, too. The CPC, based on Chairman Mao Tsetung's teachings, concluded that giving economic aid to parties was corrosive, and that it was a revisionist policy, because a Party must be self-reliant. This is what we have followed: self-reliance. Self-reliance has to do with economic necessities, but mainly, as we understand it, it has to do with ideological and political orientation. With that as our starting point we can see how to deal with the economic necessities which are always present--it would be an error to say they don't exist."
