I haven't seen this ethos specifically with respect to workers, but have definitely seen it with respect to ethically sourced materials, sustainable environmental practices, etc. It seems to work well in wealthy areas where people can afford to care about these things. It does not work at all in lower income areas, which is most of the US. Price tends to trump pretty much everything else for the vast majority of consumers.
