The determinants of worker job satisfaction are estimated using a representative survey of three major cities in China. Legally segregated migrants, floaters, earn significantly less than otherwise equivalent non-migrants but routinely report greater job satisfaction, a finding not previously reported. We confirm a positive role for membership in the communist party but find that it exists only for non-migrants suggesting a club good aspect to membership. In contrast to earlier studies, many controls mirror those found in western democracies including the "paradox of the contented female worker."
