> I wish it layed out a path of how to build an industry that doesn't attract all those ambitious selfish (executives) people

Given that ten thousand years of human history have utterly failed to produce any system at any point in time where the value-makers are rewarded over the salespeople, I don't think any such system can be made. At least executive positions aren't quite at the level of a winner-takes-all competition and you have a plausible chance of making it to that level.
