What audience did George McNeil write the poor mans burden?

There is no evidence that George McNeil wrote a poem called "The Poor Man's Burden." The poem you're likely thinking of is "The White Man's Burden", written by Rudyard Kipling in 1899.

"The White Man's Burden" was written to encourage the United States to take on the Philippines as a colony after the Spanish-American War. It used the idea of a "burden" to justify imperialistic expansion, arguing that white people had a moral obligation to civilize and uplift the "lesser" peoples of the world.

While the poem was intended to be a call to action, it was also criticized from its inception for its racist and paternalistic tone.

There was no "Poor Man's Burden" poem by George McNeil. However, there have been many parodies and responses to Kipling's poem that address the perspective of the colonized people, often using the term "Poor Man's Burden." These poems often critiqued the arrogance and hypocrisy of colonialism, while also offering a voice to those who were forced to endure its consequences.
