It's logical that people would want to defend these things because abusive labor practices are driving almost every aspect of our lives in the Western world. Our food, our clothes, our phones, our computers, our furniture, almost everything that we buy is manufactured and sold though exploitation.
People have a tendency to fight problems when they seem manageable, but labor exploitation is so out of control, the only options seem like flight into some kind of back-to-the-land movement or justification. It's too bad that this kind of mentality is so prevalent among people who think of themselves as problem solvers.
