how did the Social Security Administration discriminate against African-Americans when the benefit first rolled out

Answer with Explanation:

The Social Security Administration discriminated the African-Americans by excluding them from the program's beneficiaries. A large number of the African-Americans worked in the areas of domestic and agriculture. People who worked in these areas were deliberately excluded as a result of the racial biases that occurred during those times.

The primary reason behind this was the fact that the Congress (the lawmakers / legislative branch) acted as puppets of the wealthy people (Southern Democrats). So, the laws that they made were very supportive of the rich rather than the needy. They also didn't support any welfare system for the black people.

Thus, this explains the answer.
