The election just finished should provide all the evidence you need that people see immigration--legal and not--from a bunch of perspectives.
Peg Bowden, a former nurse, withholds judgment of the people coming into the United States from Mexico. She lives hard by the border in Arizona, and works helping people with basic survival needs in the harsh desert.
Bowden offers a view of her tasks in her book: A Land of Hard Edges: Serving the Front Lines of the Border. She visits the Rogue Valley and the Exchange to discuss work and book.
