Law or consumer pressure?

I was told that the bar code of food package would tell you where the food is from. Do you know how true it is? When I learned that you can import bulk ingredients from any country, assemble them here and label them 'Made in U.S.", I started this suspicious feeling in my guts. If the ingredients from country C can go to country N and end up killing cats and dogs in country U, the international trade business has become a black box. Shall we wait for the government to have a law to require country of origin labeling on food? Shall we push food makers to do such disclosure? But, what's their incentive for doing so?

We do need to have laws to require certain transparency in our food chain. But how long would it take? Let check into the process of COOL.
