Affirmative Action Unnecessary?

[Spexxvet]

I work in an office with 7 people. The owner is a Christian Caucasions. All of the employees are "Christian" Caucasions. This county is about 70% white

RACE AND ETHNICITY
White 70.9
Black or African American 18.1
American Indian and Alaska native 0.3
Asian 3.7
Native Hawaiian and other Pacific islander 0.0
Some other race 5.1
Two or more races 1.9
Hispanic or Latino 9.7

and we are about 2 miles from the city of Camden, NJ., which is about 17% white.

Demographics
As of the census of 2000
16.84% White,
53.35% Black or African American,
0.54% Native American,
2.45% Asian,
0.07% Pacific Islander,
22.83% from other races,
3.92% from two or more races.
38.82% of the population were Hispanic or Latino of any race.

If hiring practices were truly color blind, shouldn't this office have at least one minority working here?
Since no minority works here, is there something going on (consciously or unconsciously)?
Is it right that no minority works here, given the makeup of the local population?
