A powerful meme to complement "Occupy" would be to regularly refer to the Wall Street sociopaths as "Hoarders."
Now that TV has popularized hoarding as an illness of over-accumulation, the application of the term to ultra-capitalists who don't know when to stop grabbing and start sharing is totally apropos. They are obsessively, compulsively possessive. And as a result, paranoid. In the Wall Street Hoarders' addled world view, everyone wants to take away the lucre that they believe makes them well, but that actually makes them very sick.
So let's help the Wall Street Hoarders neaten up. Let's help them to clean up their clutter and start handing back to the people the socially generated wealth which was (and is) taken from them by the Hoarders, unnecessarily and unfairly. After all, it's in the Hoarders own long-term self-interest, and for the economy's well being that they not be so greedy and grabby, unable to let go -- and, frankly, appallingly sloven.
