I think you are too pessimistic.
I don't really disagree with you, since it's obvious that money goes to people who already have money, and I see Apple making piles of cash, and keeping it to itself.
At a given moment, the whole system will collapse, but is it really a bad thing ?
I see the advertising model as a way to create a fake good reputation.
It's easier to invent a good self-image and ignore what's wrong, and that's where Apple, Google and Facebook excel.
Hey, you are starting to rub off on me !
