the Johnson–Forest Tendency of C. L. R. James and Raya Dunayevskaya, who formulated her theory in the early 1940s on the basis of a study of the first three Five Year Plans alongside readings of Marx's early humanist writings. Their political evolution would lead them away from Trotskyism. Another is that of Tony Cliff, associated with the International Socialist Tendency and the British Socialist Workers Party (SWP), dating back to the late 1940s. Unlike Johnson-Forest, Cliff formulated a theory of state capitalism that would enable his group to remain Trotskyists, albeit heterodox ones. A relatively recent text by Stephen Resnick and Richard D. Wolff, titled Class Theory and History, explores what they term state capitalism in the former Soviet Union, continuing a theme that has been debated within Trotskyist theory for most of the past century. Other terms used by critical left-wing theorists in discussing Soviet-style societies include bureaucratic collectivism, deformed workers' states, degenerated workers' states and the "new class". Maoists and anti-revisionist Marxist–Leninists In the common program set up by the Chinese People's Political Consultative Conference in 1949, in effect the country's interim constitution, state capitalism meant an economic system of corporatism. It provided as follows: "Whenever necessary and possible, private capital shall be encouraged to develop in the direction of state capitalism". From 1956 to the late 1970s, the Chinese Communist Party (CCP) and their Maoist or anti-revisionist adherents around the world often described the Soviet Union as state capitalist, essentially using the accepted Marxist definition, albeit on a different basis and in reference to a different span of time from either the Trotskyists or the left-communists. Specifically, the Maoists and their descendants use the term state capitalism as part of their description of the style and politics of Nikita Khrushchev and his successors as well as to similar leaders and policies in other self-styled "socialist" states. This was involved in the ideological Sino–Soviet split. After Mao Zedong's death, amidst the supporters of the Cultural Revolution and the Gang of Four, most extended the state capitalist formulation to China itself and ceased to support the CCP which likewise distanced itself from these former fraternal groups. The related theory of Hoxhaism was developed in 1978, largely by Socialist Albanian President Enver Hoxha, who insisted that Mao himself had pursued state capitalist and revisionist economic policies. Most current communist groups descended from the Maoist ideological tradition still adopt the description
