And given his power in the value chain, start to demand basic rights in the crap countries of the world where the crap he peddles is made.

Steve Jobs had so much power that literally in one, single email, in one sentence, could have changed workers rights globally. His supply chain would have had to bend to his specific requirements and it would have propagated. A simple 'charter of workers rights', you know, like the 'right to go to the bathroom' and to 'not be woken up in the middle of the night' etc. would have been nice to see.
