You're not thinking insidiously enough. It'll be an excuse to raise prices across the board and then provide incentives for constant consumers that return prices to a lower, but still higher than now, point. Instead of a cold and calculating "someone making 3x as much will eagerly spend 50% more on this without thinking about it" plan it'll be "everyone pays 50% more, but good corporate paypigs get a 25% discount off of that, and if their loyalty credit score with the vendor is high enough it'll be 35%!" incentivizing both consumption and subservience while extracting more profit off of fewer commodities.

It'll be the evolution of existing "loyalty programs" and the like, not the sorts of weird idealist "market efficiency" thought experiments the high priests of capital think up when swimming in numbers and models built on flawed and nonsensical foundations. Because as everyone quickly sees, this whole concept is nonsense that implodes from outrage or gets gamed immediately - it only works in on a small scale with passive participants who don't share information or know it's happening. But the sorts of infrastructure the concept requires can easily be used the same way as existing manipulation tactics, just amplified to their logical conclusions.
