I seen some comment is other threads along this line, You can not hire someone no mater what their background is if they do not exist.
I been part of organizations who were trying to diversify for very good reason since different people from different background can bring ideas which a homogeneous group may fail at seeing. I can tell you ever single time they fail to achieve their goal. It was not because they did not try hard, they did. They even went into the communities which they were trying to hire from and promote getting the necessary skills to make them marketable. These people are not interested in being Techie, engineering scientists and so on.
In the end they still failed and Apple is destine to do the same in spite of what Cook will like to see happen. The reason is you can not hire what does not exist. People who work for Tech Companies have set of skills which not everyone in the world possess. You have to be good in math and science and most people are not good at this so it leaves a very small group of people who excel in this space. Then you have every tech company in world looking to hire that same group of people and thus the reason they get paid so well.
For the very few minorities who happen to fit the bill, they end up getting over paid since they have 10 or more companies all trying to hire them to meet these goals. in the end 9 companies fail to hire the person and the company that wins has and over price worker which they eventually figure out and find a way to get rid of them.
I agree every person should have ever opportunity to get the best job, but saying that every company should minor society is unrealistic, since some company do not match society in their make up and Apple is one of them. To say they could hire them in their stores is stupid, would you want someone waiting on you who have no clue or does not understand technologies when you have technical question. My experience with apple store people is they know their stuff and they are not their to just process your order, like someone at McDonald's.
