this view of gender oppression as a sub-class of class oppression is naive, and much of the work of Socialist feminists has gone towards specifying how gender and class work together to create distinct forms of oppression and privilege for women and men of each class. For example, they observe that women's class status is generally derivative of her husband's class or occupational status, e.g. a secretary that marries her boss assumes his class status. In 1972, "Socialist Feminism: A Strategy for the Women's Movement", which is believed to be the first publication to use the term socialist feminism, was published by the Hyde Park Chapter of the Chicago Women's Liberation Union (Heather Booth, Day Creamer, Susan Davis, Deb Dobbin, Robin Kaufman, and Tobey Klass). Other socialist feminists, notably two long-lived American organizations Radical Women and the Freedom Socialist Party, point to the classic Marxist writings of Frederick Engels (The Origin of the Family, Private Property and the State) and August Bebel (Woman and Socialism) as a powerful explanation of the link between gender oppression and class exploitation. In the decades following the Cold War, feminist writer and scholar Sarah Evans says that the socialist feminist movement has lost traction in the West due to a common narrative that associates socialism with totalitarianism and dogma. Post-1970, the socialist feminist movement continued to grow. In "Socialist Women: European Socialist Feminism in the Nineteenth & early Twentieth Centuries," by Elizabeth Lapovsky Kennedy, social feminism is defined as "women who saw the root of sexual oppression in the existence of private property and who envisioned a radically transformed society in which man would exploit neither man nor women" The equality described has to do with a transformed society in which both sexes are equal and given the same opportunities despite any physiological differences. Going forward it is described to need a total change in both the economic and social system to create the lasting improvement that the socialist feminism movement is looking for. Kristen Ghodsee argues in her book Why Women Have Better Sex Under Socialism that free markets discriminate against women as big bosses consider women to be less reliable, weaker and more emotional which leads to the gender pay gap as they need financial incentives to employ them. George Bernard Shaw quotes "Capitalism acts on women as a continual bribe to enter into sex relations for money". He also claims many
