Think it like some journalist in NYC working for a major media company goes to some manufacturing plant in the Midwest, finding people are doing hard work under not good enough conditions. And that'll give some perspectives.
A NY Times reporter covering poor working conditions in a meat packing plant in the Midwest is also a story worth reading. It happens, sometimes it changes when it's exposed, but almost never changes without exposure. An American reporting on bad American working conditions is more impactful than a Chinese reporter reporting on poor American conditions and the reverse is also true.
Upton Sinclair was able to change things with his work on The Jungle. I don't see this as being a lot different.
I actually agree. What I wanted to point out is for the reader of the story to keep in mind that the writer is a white collar Shanghai journalist, and would inevitably come with his frame of references because of it. For a NYT journalist living in NY, I believe most Western readers will assume a liberal bias, and view the reporting through some lenses, but the sophistication towards China probably stops at the reporter being a "Chinese Journalist".
Sure, the writer is more qualified than you and me, but he didn't answer some critical questions - is this factory above or below average in Chinese manufacturing plants? Is Foxconn raising or lowering labor standards in the area? Is Foxconn providing better alternatives to local labor, who may have to make a living by going down a tunnel in a coal mine or planting rice under the sun? Is having the plant there better or worth than not having the plant there?
