The Moral Framework for the Occupy Wallstreet Movement by George Lakoff

Two Moral Framing Systems in Politics
Conservatives have figured out their moral basis and you see it on Wall Street: It includes: The primacy of self-interest. Individual responsibility, but not social responsibility. Hierarchical authority based on wealth or other forms of power. A moral hierarchy of who is "deserving," defined by success. And the highest principle is the primacy of this moral system itself, which goes beyond Wall Street and the economy to other arenas: family life, social life, religion, foreign policy, and especially government. Conservative "democracy" is seen as a system of governance and elections that fits this model.
Though OWS concerns go well beyond financial issues, your target is right: the application of these principles in Wall Street is central, since that is where the money comes from for elections, for media, and for right-wing policy-making institutions of all sorts on all issues.
The alternative view of democracy is progressive: Democracy starts with citizens caring about one another and acting responsibly on that sense of care, taking responsibility both for oneself and for one's family, community, country, people in general, and the planet. The role of government is to protect and empower all citizens equally via The Public: public infrastructure, laws and enforcement, health, education, scientific research, protection, public lands, transportation, resources, art and culture, trade policies, safety nets, and on and on. Nobody makes it one their own. If you got wealthy, you depended on The Public, and you have a responsibility to contribute significantly to The Public so that others can benefit in the future. Moreover, the wealthy depend on those who work, and who deserve a fair return for their contribution to our national life. Corporations exist to make life better for most people. Their reason for existing is as public as it is private.
A disproportionate distribution of wealth robs most citizens of access to the resources controlled by the wealthy. Immense wealth is a thief. It takes resources from the rest of the population - the best places to live, the best food, the best educations, the best health facilities, access to the best in nature and culture, the best professionals, and on and on. Resources are limited, and great wealth greatly limits access to resources for most people.
It appears to me that OWS has a progressive moral vision and view of democracy, and that what it is protesting is the disastrous effects that have come from operating with a conservative moral, economic, and political worldview. I see OWS as primarily a moral movement, seeking economic and political changes to carry out that moral movement - whatever those particular changes might be.
