That might be, but how many people tweet about social justice concerns using their iPhones, and yet cast no light on these problems? Globalization on it's own

That might be, but how many people tweet about social justice concerns using their iPhones, and yet cast no light on these problems? Globalization on it's own isn't enough to improve human rights as long as there's a commercial incentive to suppress them. People taking an interest, making purchasing decisions, putting pressure on companies, voting in line with these ethics in mind, etc. can have some impact. This idea that we can just sit back and let economics improve quality of life -- at least at the very bottom -- seems a little naive.
