Inequality and government policy

Failed government policy increases inequality when politicians push dis-similar needs of disparate groups onto central government. This is the most common failure mode.

Thing that map to DC and thing that don't:

Social Security seems safe because it has a similarity across the continent. Much of specialty medicine does not map to DC. Emergency room medicine is standard across the continent, and may well map to DC. Monetary policy does not map well to DC is the real world does not map well to DC. Earmarks, on a congressional basis might map, I think so but could be proven wrong.
