human rights and profits are connected... we have laws against 1$ salaries, minimum wage laws, laws against certain working conditions, unions etc.
the only chance i see of stopping this trend is when sometime in the future, "cheap" labourers in developing countries stand up and demand similar rights to the ones in developed countries. though that might take some time, and it might well be too late (as in: the developed countries already lowered their standards) by then.
