Social movements arise to solve problems of inequality, injustice, exploitation and oppression. In other words, they are solutions to society-wide problems plaguing the many but not the few (i.e. the elites at the top of the wealth-power pyramid).

The basic assumption of social movements is that Utopia is within reach, if only the sources of the problems can be identified and remedied.  Since inequality, injustice, exploitation and oppression arise from the asymmetry of power between the few (the financial and political elites) and the many, the solution is a reduction of the asymmetry; that is a tectonic realignment of the social structure that shifts some power—economic and/or political—from the few to the many.

In some instances, the power asymmetry is between ethnic or gender classes, or economic classes (for example, labor and the owners of capital).

Social movements are characterized by profound conflict because the beneficiaries of the power asymmetry resist the demands for a fairer share of the power and privileges, while those who’ve held the short end of the stick have tired of the asymmetry and refuse to back down.

Two dynamics assist a social, political and economic resolution that transfers power from those with too much power to those with too little power: 1) the engines of the economy have shifted productive capacity definitively in favor of those demanding their fair share of power, and 2) the elites recognize that their resistance to power-sharing invites a less predictable and thus far more dangerous open conflict with forces that have much less to lose and much more to gain.

In other words, ceding 40% of their wealth-power still conserves 60%, while stubborn resistance might trigger a revolution that takes 100% of their wealth-power.

History provides numerous examples of these dynamics.  Once the primary sources of wealth-generation shifted from elite feudal landowners to merchants and industrialists, the wealth (and thus the political power) of the landed elites declined. As the industrialists hired vast numbers of laborers drawn from small farms and workshops, this mass industrialized labor became the source of the wealth generation; after decades of conflict, this labor class gained a significant share of the wealth and political power.

The civil rights and women’s liberation movements realigned the political and economic power of minorities and females more in line with their productive output, reducing the asymmetries of ethnic and gender privileges.

In broad-brush, progressive social movements seek to broaden opportunities and level the playing field by reducing the asymmetric privileges of dominant classes defined by power and privilege.  The core mechanism of this transition is the recognition and granting of universal human rights: the right to vote, the right to equal opportunity, and rights to economic security, i.e. entitlements that are extended universally to all citizens for education, healthcare, old-age pensions and income security.

Again in broad-brush, these movements have largely been categorized as politically Left, though many institutions deemed conservative (for example, various churches) have often provided bedrock support for progressive movements.

Social movements which seek to limit the excesses of state power tend to be categorized as conservative or politically Right, as they seek to realign the asymmetry of power held by the state in favor of the individual, family and the traditional social order…..More Here
