"Not only was Wonder Woman a more enduring character than Rosie, her contribution to the war effort was also more direct. Rosie's war job was to make planes, weapons and ammunition that would help men win the war. She was the quintessential woman behind the man behind the gun, Wonder Woman, on the other hand, fought alongside men on the front lines of battle; she was the woman who led the man who held the gun. Defying convention that relegated woman to the role of man's submissive helpmate, Wonder Woman fought not for men, but for liberty and freedom and all womankind!" (Marston and Peter, All Star Comics #8, 15). Whereas Rosie suggested that women work in order to help men, Wonder Woman encouraged women to work because it enabled their independence from men. When misogynistic Dr. Psycho hypnotizes his wife, Marva, and forces her to help him in his plot to enslave American women in Wonder Woman #5 (Jun./Jul. 1943), Marva bitterly laments: "Submitting to a cruel husband's domination has ruined my life! But what can a weak girl do?". Wonder Woman of course, has the answer: "Get strong! Earn your own living- join the WAACS or WAVES and fight for your country! Remember - the better you fight, the less you'll have to!" Because Marston believed that women's economic independence was a necessary step towards their empowerment, he used Wonder Woman to encourage women and girls to pursue work outside of the home for the sake of their own autonomy and personal fulfillment. In doing so, his character directly challenged traditional gender roles in a way that Rosie did not."
