This individualistic attitude is how we got to our current situation, and why we are perpetually stuck here. Everyone in any position of corporate power is a psychopath, because the system will replace them if they are not. Every purchase you make has the downstream effect of encouraging whoever you bought it from to continue doing what they are doing. And, what everyone is doing is "throwing everything possible (morally, ethically, and legally) under the bus to grow profits." Individuals don't get to dodge culpability just because we are only indirectly funding all this bad behavior.
Absent government will (which has been the reality for decades), we have no way of stopping this bad behavior than to stop funding it. But since nearly every company is engaging in bad behavior, "stop funding it" means becoming a hermit and not buying anything, which is also not feasible for enough people.
Becoming only consumers is how we got here. We are no longer citizens, no longer members of religion, no longer anything but consumers. Hiker/biker/crafter/music maker...so much around the scene is consumption. So all we see is consumption. To the point that making the tiniest movement in consumption is the only impact we can possibly imagine. Every good company sells out in the end. You aren't making a difference, you are building someones brand.
Don't play that game. You aren't a consumer you are a human being. Today you can impact for the positive. Choose your shopping based on savings/health, and invest that money into your local foodbank or helping someone at something like Kiva.org (I don't keep up, is Kiva bad now?) or other local charities where you can actually have an impact.
It's crazy how people have been convinced to give up and do the most barely needle moving things to feel moral.
There are these child-sized shopping carts at the grocery near me with a flag on them that says "customer in training", and it's one of the sickest most obscene thing I can think of. Because it's true, we train our children to be good consumers better than we train them to be good citizens. And it shows.
