It's not how much...
...El Reg do or do not care, it's how much we as consumers care. We want low prices, and someone has to pay for that. Why do you think our t-shirts, trainers etc are so cheap? We're not paying the true price, some of the cost is absorbed by human misery.
If the price of a phone from company X rises dues to this and the equivalent from company Y stays the same because they go to a different manufacturer, then consumers will switch to Y and company X goes down the toilet. Consumer demand will force companies to move to the cheapest manufacturer, regardless of working conditions.
Even for consumers who do care, there is no way for them to be sure if it's company X or Y actually who have decent working conditions. For all they know, company X could be taking the piss or company Y may simply Actiobe more efficient. One can't exactly buy "FairTrade" mobile phones.
One could say that company X should take a small hit on profits to ensure decent conditions, but then dividends and share price drop, investors leave and one bitches about one's pension.
The only thing that can really be done is to keep exposing the exploitation until it becomes too risky for companies to even consider dealing with such manufacturers.
Did you, or anyone else reading this, avoid purchasing anything made by Foxconn because of worker conditions (e.g. Apple products, Nokia phones)? Did anyone write to the relevant CEOs and say why they were boycotting their products? Nope, me neither.
It's a sick, sad world; but it is so easy to ignore what goes on when it is "over there".
