What I'm pointing out is that Apple puts forward a green image that is at best inaccurate and at worst misleading, but anyway:
Clout is not infinite - if Apple pushes Foxconn to be greener, Foxconn will charge more money.
Yup, it's about the bottom line - beyond a certain point (e.g. efficient usage of materials), green cuts into margins. It's not unreasonable to think that Apple subcontracts what it can to China for more reasons than cheap labor.
In that context why don't you find a greener job, or bike to a farmer's market? It's much easier to underestimate the cost of a sacrifice that you ask someone else to make than than a sacrifice you make yourself. The reason for this is that you're aware of the details involved for yourself, but view Apple from far away where everything is rounded and shiny.
Greener markets: check (farmers drive all the way from other states). Greener jobs: none in my line of work. There are not even many recycling containers in this country since things went downhill. Plus some products are certainly out of our control (green electronics?). I sacrifice what I can - not throwing away what I can mend or repurpose, print only what I must, CCFL, etc.
