a very instructive history of 20th century social movements - specifically, the unemployed movement of the Great Depression, the industrial workers' movement of the 30s, the civil rights movement, and the welfare rights' movement of the late 60s.
Piven's argument is that movements succeed through disruption (direct action). disruption causes elites to have to appease movements with reforms, whereas negotiating, lobbying, or other tactics are more easily ignored. Piven also contrasts disruption with attempts to build "organization", which is presented as the bugaboo. what is meant by "organization" is hierarchy and bureaucracy. movements that fell into hierarchical institutional patterns, such as the ones highlighted in this survey, generally became co-opted by the system and lost their radical edges. consequently, they were no longer able (or interested) to make real change happen, and became more about managing constituencies. the classic case is the labor movement, where labor leaders became another part of the restraining apparatus against workers' militancy.
however, i bristle at the sweeping attack on "organization" itself. does Frances Fox Piven know nothing of nonhierarchical, directly democratic organizing? surely she isn't so inexperienced. instead, the book reads as an overreaction against the insanely hierarchical and bureaucratic National Welfare Rights Organization (NWRO), which Piven and Cloward were heavily involved in until the 70s, when this book was written. it's as if their experience there left such a bad taste in their mouths that any positive associations with genuinely radical, democratic organizations such as the IWW, SNCC, or SDS, were tainted in their minds and no longer worth considering.
in summary, if one substitutes the words "hierarchical/top-down organization" for the overly broad "organization" found throughout the book, this actually becomes a very helpful summary of where some key movements in the 20th century made huge inroads, only to become part of the system they originally set out to topple.
