We do care. I get really annoyed at this argument.
We cared so much about the welfare of our fellow man, that we passed laws ensuring that companies needed to run safe, healthy, ethical and environmentally friendly environments.
We did this despite the prospect of higher costs, because we cared.
Companies then moved their manufacturing (and mining!) to other countries, where they could continue to abuse the people and their environment in peace to ensure bigger profits for themselves.
Somehow this is now our fault again.
Tracking and maintaining a record of every single company whose goods we should avoid is HARD, and most of us already have too many things we need to do.
We have consistently indicated that we want our government to help us ensure that the goods we consume are produced ethically, safely and in an environmentally friendly way.
The problem is that there is no will at the government level to do this.
