Labor markets don't evolve via discontinuous jumps to higher levels of pay or better working conditions. It has to be an incremental process. I'm not sure how berating companies that are enabling those incremental improvements for not doing enough is helpful. And using a pejoritve term like 'exploit' rather than 'employ' shuts down meaningful discussion. Maybe I'm wrong though. Any examples of labor markets magically transforming from 'sweatshop level' to 'McMansion/Country Club level' without going through the intermediate steps?
