Per the banker analogy, it'd be like if the banker hired all of the personal trainers so other bankers wouldn't have access to them, give most of them nothing to do because it turns out the banker only needs one, and then fire them all once the other bankers won't be able to hire them as easily, all without any regard for the impact this strategy has on the trainers' lives and without being upfront and honest with the trainers about the strategy.

Yes, that's greedy.
