Gorbachev's perestroika also entailed attempts to move away from technocratic management of the economy by increasingly involving the labor force in industrial production. He was of the view that once freed from the strong control of central planners, state-owned enterprises would act as market agents. Gorbachev and other Soviet leaders did not anticipate opposition to the perestroika reforms; according to their interpretation of Marxism, they believed that in a socialist society like the Soviet Union there would not be "antagonistic contradictions". However, there would come to be a public perception in the country that many bureaucrats were paying lip service to the reforms while trying to undermine them. He also initiated the concept of "gospriyomka" (state acceptance of production) during his time as leader, which represented quality control. In April 1986, he introduced an agrarian reform which linked salaries to output and allowed collective farms to sell 30% of their produce directly to shops or co-operatives rather than giving it all to the state for distribution. In a September 1986 speech, he embraced the idea of reintroducing market economics to the country alongside limited private enterprise, citing Lenin's New Economic Policy as a precedent; he nevertheless stressed that he did not regard this as a return to capitalism.
