I found the mention of Marilyn Monroe and the description of her father with use of economic metaphors and the immigrants arrival at Ellis Island historical references.
I think materials that describe the 1930's would lend credence to the contents of this poem.
That's true, especially the Angel Island reference. It strikes me that this poem could be a great introduction to Amy Tan's Joy Luck Club, or to Laurence Yep's Dragonwings, both of which involve Chinese immigrants coming to the US.
