The Plutonomy

n. An economy that is driven by or that disproportionately benefits wealthy people, or one where the creation of wealth is the principal goal.
[Blend of pluto- (wealth) and economy.]

Read (get past the beginning of) this dkos post.
The main fear Citigroup has is that since one person-one vote still obtains, the rich have only 1% of the vote, and that may eventually end the plutonomy.  Presumably there are corporate skunkworks to try to remedy the situation.

Citigroup Plutonomy Report Part 1

- The World is dividing into two blocs - the Plutonomy and the rest.   The U.S., UK, and Canada are the key Plutonomies - economies powered by the wealthy. Continental Europe (ex-Italy) and Japan are in the egalitarian bloc.
- Equity risk premium embedded in "global imbalances" are unwarranted.   In plutonomies the rich absorb a disproportionate chunk of the economy and have a massive impact on reported aggregate numbers like savings rates, current account deficits, consumption levels, etc.
This imbalance in inequality expresses itself in the standard scary "global imbalances". We worry less.
