Ethical Hekhsher

The Forward is reporting that leaders of the Conservative movement are planning on creating a new certification for food that ensures the rights of workers who produce the food (link). I question what benefit this will have to anyone. The producers will only care if a lack of such certification causes them economic harm. But, realistically, how many consumers will really start demanding this certification? Perhaps Conservative synagogues will start insisting on only using caterers that adhere to this certification. But if it becomes too much of a burden, caterers won't do it and synagogues will be stuck. This is especially so in smaller communities where kosher food is hard to come by.

Maybe I'm wrong on this. But did anyone do an economic study on this before submitting this proposal? Because I just don't see it as working.
