This piece from my printmaking studio was premised on the theme of "difficult differences."  I was thinking about the American idea that, as a superpower of the world, we are responsible for the rest of the world.  This is a very romantic idea and I believe that 'we' use it to justify invasive actions that will, theoretically, benefit us, or a choice few, financially.  I used Mexico as an example of a people who need and want our help, but we demonize them because they benefit us more if they stay where they are and provide a cheap source of labor.
