You can TRY.
I buy specific New Balance shoes, because they're made in America and theoretically made under some labor laws. I buy my clothing second hand. At least I'm not the one who payed the blood price on them. I try to buy local food, or at least Organic. I ride my bike and take public transportation as much as possible. When I need to buy a power tool, I hit Craigslist and buy an older (and usually better made and cheaper to boot) tool instead of buying new. My computers are bought second hand as well. A four year old Laptop surfs the web, programs, and does CAD work just fine. Etc.
Blah blah, I'm awesome... the point is, you can TRY. If consumers shifted their consumption patterns just a LITTLE bit, it would send a big message. Just look at food. 15 years ago, the concept of an Organic isle in Safeway was inconceivable. Look at chocolate. Fair trade is better than not fair trade. Even buying from the same company, but Organic, means that company is behaving better. People wanted better chocolate, and they wanted to feel like they weren't taking advantage. The market shifted in response.
Or you could just not care, because there's nothing you can do. I think that's the biggest lie we as Humans have to overcome. There is PLENTY you can do. Amazing things happen when folks organize and share effort.
