 In 1929 Reich and his wife visited the Soviet Union on a lecture tour , leaving the two children in the care of the psychoanalyst Berta Bornstein . Sharaf writes that he returned even more convinced of the link between sexual and economic oppression , and of the need to integrate Marx and Freud . In 1929 his article " Dialectical Materialism and Psychoanalysis " was published in Unter dem Banner des Marxismus , the German Communist Party journal . The article explored whether psychoanalysis was compatible with historical materialism , class struggle and proletarian revolution . Reich concluded that they were compatible if dialectical materialism was applied to psychology . This was one of the central theoretical statements of his Marxist period , which included The Imposition of Sexual Morality ( 1932 ) , The Sexual Struggle of Youth ( 1932 ) , The Mass Psychology of Fascism ( 1933 ) , “ What is Class Consciousness ? ” ( 1934 ) and The Sexual Revolution ( 1936 ) .
