Consumers almost never care outside of isolated causes du jour or when it directly affects someone they know. Look at all the self-proclaimed socialists and progressives walking around with iPhones manufactured by Foxconn, a company known for treating its employees so badly there were inquiries into the suicide rates of their workers at one point.
While I have my concerns about unions, they are absolutely necessary in many cases. Companies are not your friend, nor are your fellow consumers most of the time.
