We argue that women in the care workforce face a wage penalty because care work is perceived as something that people, especially women, are meant to do out of love (and for free). We focus on care labor, which is aligned with stereotypes about women's natural abilities as caregivers, to show that low wages cannot be explained by counter-stereotypic behavior alone. Instead, low wages in care labor can be explained by a perceived love versus money tradeoff. This tradeoff exists not only because of intrinsic rewards and fears of commodifying care but because of the idea that trading love for money amounts to trading the sacred for the profane. In other words, care workers are underpaid because many people, either implicitly or explicitly, perceive the very act of making money as counter to care, a stereotypically-feminine form of work. This stereotypical association contributes to the gender pay gap more generally because it implies that the work women are suited for is work that should be done for free. We expand on this idea with future directions and practice implications, which include building communal spaces for care workers to facilitate communication and organizing around higher pay and better working conditions.
