For years I've been thinking about forcing a change to the Consumer Packaging and Labelling Act mentioned here by issuing a charter challenge. My stance would be that not forcing company's to list all countries of origin and the percentage of material and labour that they make up denies me the information I need to make an informed decision. I have a right to this information so that I can express my support for or against areas of influence that affect my life. Anybody think this would work?
Some foods have over 20 ingredients in them, and many products have ingredients or materials that exchanged hands multiple times before it's manufactured.
Currently, Made in... Product of... Packaged in... All have defined parameters.
Do I think this can be made better or more transparent? Sure. But unlikely as granular as you're suggesting.
In today's political climate, it would simply make sense (and dollars) for retailers and manufacturers to be more open about where products come from.
Ultimately, consumers will spend money how and where they want, and these companies follow that money.
I understand the many inputs that are involved but if you take the accounting side of things it would take nothing to identify a % for each country involved. The difficulty you suggest sounds more like a marketing complaint. Company's have all been only to quick lately to demonstrate how convenient it is to change their packaging.
I'm a lazy, not so bright contrarian who doesn't know the details enough to have formed a sensible defense. What I do know is that I have a right to express my beliefs through my patronage and I'm currently being inhibited in that effort by the intentional obfuscation of the information I need.
