According to the speaker of the poem "Harlem", his job prospects are slim because

he has no marketable skills

there are no job opening in his area

the government is oppressing him

no one will hite African Americans

The correct answer is: the government is oppressing him.

Explanation:

This short poem, published in 1951, during The Harlem Renaissance, describes the way that government is oppressing African American citizens. Due to the oppression, the poet has to put all his wishes and hopes on hold and states how unachievable dreams will destroy him. He mainly alludes to the African American tendency to liberate themselves from racism and slavery, but there is always the supremacy of the (white) government which does not allow them to be independent and well-respected citizens.
