So Mexican's are Taking Jobs from Americans

I really thought that this poem was terrible, It starts off talking about how Mexicans are taking jobs away from Americans, and then it goes into small farmers selling out to "clean -suited farmers living in New York" (line 26&27) who are shooting "blacks and browns whose ribs I see jutting out and small children" (lines 21-23). I think that the author should have stuck with a topic that actually pertains to multiple jobs and not just farming. The author is almost making it seem like all that Mexicans do is farm, and that's where the American people think they are taking our jobs from us. There should have been a better example than just farming, cause the view of the author is hard to see from the text that was used.
