This paper examines the relationship between social class and social m
obilization through reviewing the case of new social movements. The mi
ddle-class membership of new social movements is well documented but p
oorly explained by current New Class, New Social Movement, and Cultura
l Shift theories. These theories fail to recognize the interdependence
between interests, values, and expressed ideas. Class culture provide
s an alternative framework for interpreting the complex relationships
between class interests and consciousness in these movements. Through
a comparison of working-and middle-class cultures it is proposed that
social class orders consciousness and shapes the interpretation of int
erests. Class cultures produce distinct class forms of political and o
rganizational behavior. while not defining any particular content of m
ovement issues or politics. In particular; the middle-class membership
of new social movements is explained by the cultural form of these mo
vements which is distinctly middle class.
