No repetition, but rhyming
From Understanding Society:
So Dynamics of Contention offer a serious methodological alternative to all of the theories of revolution mentioned here: rather than looking for a small number of structural characteristics that "cause" or "inhibit" revolution, we are better served by moving down to the meso- and micro-levels of mobilization, claim-making, repression, state building, tax collecting, and ideological competition that constitute the real causal stuff of revolution and contention.
It is worth observing, further, that the Dynamics of Contention approach -- identifying discrete mechanisms and processes of contentious politics -- offers vastly better resources for investigating and explaining the wave of revolts, uprisings, and popular movements that are taking place today across the Middle East than any single theory of revolution would provide. The processes of grievance-making, group mobilization, communication, escalation, brokerage, and state tactics of repression that MTT describe are of obvious relevance in trying to understand the last few months of unrest in Tunisia, Egypt, Bahrain, Libya, and other countries. In particular, none of the macro-theories -- class conflict, state breakdown, or crises of the modernizing state -- seem to shed much light on these events. What is occurring seems to be much more akin to the path-dependent, multi-causal kind of process that McAdam, Tarrow, and Tilly describe.
This connects to what Jack Crow says here. Needs further testing.
