Because the person they hired for that job lied on their CV and at interview to get the job, and if they lied on their CV about having a certain specific set of skills, they *shock* may well have lied about lots of other things.
So now they put the job back up, maybe asking the other interviewees is they are still available. Still not realizing that by having such a specific set of requirements, almost noone is qualified and the few people who are, aren't going to settle for the wage offered.
And so everyone who does pass the filter is a liar, only ever interviewing liars.
Actually, before Apple, the publishers were making exactly the same amount of profit, because they were selling them at a fixed price to the retailers.
However, Amazon was quite happy with a ~2% profit margin, and so were selling ebooks quite cheaply.
But this could give an impression that books were not as valuable as the publishers would like, and so were quite happy to collude with Apple when they wanted their 30% profit.
This impression of value is why garment labels hate grey imports. The market will bear $100 labelled jeans even though it only costs them $8 to make, _if_ there is an impression of exclusivity/value. But this impression is broken when a grey market seller decides to sell the same product for $50 - the same price as a lower tier label.
Imagine chess replacing actual war.
We'd use drones then too.
The BAU would be scanning eye movements and microgestures of the opponent.
The NSA generate a mental model simulating the opponent.
The CIA would drug the opponent and kidnap his family.
The TSA would anally probe them entering the country.
And NASA would move the board to the moon.
Hackers of the world, unite!
