Viva Mexico - Shakespeare's Monkeys

In s5, slight tightening by putting this line:

and the pick-up trucks of rednecks blast Garth Brooks,

into active voice:

and rednecks blast Garth Brooks from their pick-up trucks

You can remove the word "all" from:

The wetbacks all toil in the fields,

I'd consider putting all of the Spanish lines in italics, which I forgot to mention earlier:

"Miha, esto es el sueño Americano"
"My love, this is the American dream"
as she shrugged shrivelled green mangoes into her cart.

*s6 I think it's the girl, but I'm honestly not 100% sure if the thugs or the girl are crying, "Soy solo un gringa sucia." The reason: I know enough Spanish to get to here, but I don't know what "sucia" is. I think you need a line in English as well as you did in preceding stanzas.

I think you can tweak the line:

of her virgin's blood on the concrete;

to something like:

of virgin blood on concrete

Jasmine, this is a wonderful, wonderful poem.
