Trolling much?
What has charity got to do with ethical treatment of employees in your supply-chain?
I think the idea is that you might give the employees a bit more than just enough to buy food. Invest in the the Chinese economy so that the people there can do more. Perhaps spend some time educating themselves rather than spending all day every day on the production line. Perhaps they could lend some of the wealth you have allocated to them to a nephew who has a bright idea for a new business in the local community.
Businesses concentrate wealth, they re-allocate it. It is people doing useful work who create it. All those billions apple has represent the work and wealth previously owned by apple customers. If they hadn't bought an iphone, they would probably have spent the cash on something else. Perhaps cinema tickets or fruit and veg. Just because apple has gained a large slice of the pie, doesn't make the pie bigger.
Any wealth apple has created comes from increased productivity of apple-phone users as compared to non-apple-phone users. Undoubtedly this has happened, but probably not to the extent indicated by Apple's bank balance.
Add to that the Western propensity to earn not from creating things, but from stopping people from using ideas or doing things and you have a very shaky economy indeed.
Don't confuse wealth-possession with wealth-creation.
