I've been working on a policy inititaive for one of class assignments, it is addressing the issue of food and the differences in quality and pricing. While researching, I came across a policy written by the green party about food, titled Greening the food basket. Ironically it's main points are exactly what my main points were, but better. Here's the link, this is what the standard of our food should be and despite how much income you earn, the quality of food that you buy is the same for everyone.
The demand for better quality of food is based on peoples increasing awareness of the impact on the enviroment, peoples hardship due to the way it's produced and the effect on one's health. The more people are aware and educated on the subject, the pressure remains to change the current to better standards of how our food is produced. A movie called Food Inc has been released in America, soon to be available here.
