Fast Food Nation does not take a stand on how immigration policy ought to be handled. It does deal extensively with themes like:
I bought this film used for $6.67 my local video store. I'd encourage folks that enjoy films that are concerned about illegal immigration to add this video to your library. It will bring up a lot of discussion points-and it is a film that you could loan to even a liberal friend.
I tend to think that the most graceful way we get ourselves out of the illegal immigration mess is by a transitional phase of allowing existing folks temporary work visas, tightening the borders and gradually improving working conditions, legal rights and visa fees for workers such that use of guest worker labor gradually become less and less profitable for corporations to use. I also expect at some point, we'll need campaigns to boycott companies that use illegal alien labor-but package this program so that it isn't a disaster for Mexico and our other Latin neighbors.
The left has a much more successful track record of those kinds of boycotts than the right has—and films like Fast Food Nation are the means by which the left is starting to become conscious of the issue of illegal immigration. We need a lot more cultural material to start to really address the issue of illegal immigration and Fast Food Nation is a start.
