Not all companies which have the monopoly in a certain industry are as vile as Apple. Forget the stupid, over priced, over marketed, out of date technology Apple sells, the company itself is less than responsible for the well being of their employees. Their products are largely made by foxconn, a Taiwanese manufacturing company based in China, meaning apple outsource all of their manufacturing to third parties. This is not as commonplace as one would think, especially in the phone industry. In fact I think the only other people who get their phones outsourced is Sony, also to foxconn, but HTC make most of their phone in house in Taiwan, Nokia make theirs in China, in house, same with Samsung, and LG make their higher end phones, again in house, in Korea. This ensure quality control and correct specifications of the build of their products.
Foxconn have been in the limelight a lot in recent years due to the suicide at their facilities, by the workers who cant bare to work/live their any longer. They feel they have to however, to provide for themselves and their families. In all honesty, lack of regulation in China especially when it comes to foreign investment in manufacturing is deliberately thin on the ground, to drive in more investment. This means however that the companies who run the factories can literally get away with blue-murder, enforcing ridiculous terms and conditions and work loads never seen before in the western world. But that is what Chinas economy is based around, so as long as it works for them, who cares right ? The UN don't intervene at all.
Unlike Microsoft and a lot of other US multinationals, Apple has no recorded event of ever giving money to charity. Not that it is strictly necessary, but it holds a company in higher value, especially towards the public.
For the record, Dyson make their vacuums in house in their own facilities in conjunction with a singapour based industrial group. Dyson make their digital motors in house as well, only importing the suction motors from Panasonic for their vacuums. I also know Miele make everything in house, from the motors to the wheel bearings, as do numatic. Sebo I believe make nearly everything themselves, but use Bosch motors now I believe, someone correct me if I am wrong. Of course Kirby make everything themselves as well.
