After the Russian Revolution, Gordon worked as a freelance journalist specializing in the topic, contributing articles to Harper's Magazine, the North American Review, and other publications. Her entry into the journalistic orbit brought her into contact with Simeon Strunsky, an essayist and member of the New York Timeseditorial board, whom she later married, legally taking her husband's surname while continuing to use her maiden name as a pen name. The couple would have two children. In the years immediately after the October Revolution, when the Bolsheviks were murdering fellow socialists as assiduously as they were murdering conservatives in the Russian Civil War, Gordon critiqued their reasoning: The continual development of the Revolution to form Soviet culture and the Soviet economy was an ongoing source of fascination in the United States throughout the decades of the 1920s and 1930s. Demand existed for reporting and analysis of what was happening in the USSR. In the 30s Strunsky began work on a monograph dealing with the evolution of treatment of the working class before and after the advent of Bolshevik power. This was published in 1941 as Workers Before and After Lenin by prominent New York publisher E.P. Dutton and Company. In the book Gordon's "bottom-up" attention to the lives of common people rather than the intricacies of high politics anticipated the turn to social history during the 1960s and beyond in the field of Soviet Studies. In Workers Before and After Lenin Gordon made use of Soviet sources of economic data in arguing that under the Communist regime the standard of living of the working class had deteriorated substantially. The point of using Soviet-issued data was that even the government's own rosy numbers showed a deteriorated reality, precluding any rebuttal by Soviet officials or their supporters along the linesthat the analysis would be wrong for having used flawed data. Gordon showed that the purchasing power of wages in the late 1930s stood at only about 75% of the food value purchasable by Russian workers in the years immediately preceding World War I. Nominalwage gains had been more than offset by large price increases, including of staple goods, while consumer goods were shoddy and in poor supply, Gordon argued. She also made the point that it would have been historically realistic to expect economic growth in the decades since the prewar years, meaning that Soviet performance needed to be judged not just on comparison with 1910 standards but also on comparison with the opportunity cost of forgoing a more February-oriented existence between 1917 and 1941, which October forestalled. She then pointed out that meanwhile political freedom had degraded to virtually zero, and although the very point of the existence of trade unions is to protect workers' interests from undue exploitation by their employers, the trade unions in the Soviet Union had become totally unable to do that, as they were completely controlled by the abusive employer, namely, the state. A strikingly poignant epigraph on the title page of the book showed the depth of irony in what the Soviet regime had become by 1941; Gordon silently held up Lenin's own words alone, which formed an indictment: A second book, How to Tell Progress from Reaction: Roads to Industrial Democracy, was published by the same publisher in 1944.
Manya Gordon Strunsky died of a heart attack on December 27, 1945 in New Canaan, Connecticut. She was 63 years old at the time of her death. She left a legacy of evidence-based political and historical analysis that showed the squandered potential of the February Revolution and how a humane and progressive type of social democracy—which, as a center-left position, is often attacked and disparaged from both left and right—belies the flaws of its detractors' arguments.
