Milton Friedman should have known better than poo-pooing social responsibility and seeing it as "subversive" to a free market and thereby to a free society.
Rather he should have considered that the "Invisible Hand" powered by a nobler Consumer could bring even greater upliftment to the world.
The article below argues for CSR being 'ingrained' in the operations of the business, in its products and services, rather than as 'something separate' that had better be seen to be there in case the Consumer buys less.
The further the Consumer moves on from the Survival Coal Face, the more compassionate and caring the Consumer becomes for others - well, that is most Consumers when they are not trapped in some kind of supremacist arrogance due to culture, race or creed.
Compassion is actually within our DNA - inherent within us, but also suppressable through the poison of hateful ideologies.
