Not only should all centralized Federal offices be located in Washington, but the District of Columbia should contain nothing BUT government buildings. Concentrate all Federal functions and monuments in one contiguous area, and return the rest of the city to Maryland.
The District of Columbia should have a population of zero, and no private-sector employment. This should be written into the U.S. Constitution — in an amendment that also eliminates DC’s electoral votes.
“...Not only should all centralized Federal offices be located in Washington..”
I think only the Departments of Defense, Justice and State should be headquartered in WDC. The others should be scattered throughout the country - each Department to a different city.
