Major food for thought. I highly recommend this article. It's lengthy but worth the time. http://counterpunch.org/santos07292006.html It would be interesting to discuss this at The Conversation sometime.
The Conversation is a group of Tacoma and South Sound residents committed to the building of a diverse, critically engaged, social justice community for the task of procuring for ourselves and our communities a better life. With "Justice for All" as its foundational principle, the group has two primary foci; providing encouragement and support for social justice activists and promoting justice in such areas as legal system, wages, housing, healthcare, and education.
