Answer:
This song relates to slavery in the United States because it questions how white people can see the suffering of slaves and do nothing
Step-by-step explanation:
The music implies that whites and blacks are brothers, belong to the same species and are human beings capable of feeling the same feelings and sensations. For this reason, the music questions how the spirit of the free (the spirit of the white people) can live in peace, seeing their slave brothers living in misery and violence and doing nothing to help and free these people.
