By nature all human beings want to have more, that is how we survive. Fortunately there are some who want more but also want to help others. We do overtime to get more, whether it is a new TV or simply more food.
You mention Steve Jobs and Chinese workers but it is us as individuals that demand cheap products. Over here Primark has risen from nothing to super trendy even though it has been shown far eastern sweat shops make the clothes. Boo Hoo have been shown to be party to virtual slave labour in this country, has any woman stopped buying their clothes ? The answer is in the fact their share price has gone up. If we want change we have to do something about it and change our habits. One thing I have done this year is cancel my Christmas, no one elses, just mine. I just see it as blatant commercialism which puts families into debt, we eat/waste to much, throw tons of plastic away after unwrapping useless presents we dont want or need and then moan when the Amazon founder is declared the richest guy in the world.
Our attitude has to change if we dont like the fact it is us that make people rich.
