Depends if you believe that safe work environments are human rights, or just for Americans.

Standards yes - these should match standards of countries they sell in (or even better take the high road and just match Europe). Chinese wages are on their way up anyway and if anything, improving standards will keep wage costs down as part of the package (and I strongly believe improved standards would improve productivity/quality to more than offset costs). It's win win.

Bear in mind people are ready to queue up to pay a ton more for Apple on the basis that they strive to produce a better product on all dimensions - they are the poster child for quality across the board being a viable business approach. That should go consistently through the products and services like a stick of rock and include things like work conditions and green manufacturing.

We should be encouraging everyone to have decent working conditions.
