Dynamic pricing, in theory, isn't a bad idea. But they screwed up the application of it. The algorithm that determines the price updates of players used the ownership percentage as the basis. The problem was that the initial ownership percentage was used for each quarterly update... so the SAME players had their salaries go up at each pricing update.
Although the powers to be were eventually made aware of this problem, they either don't have the resources to fix it, or don't care enough to fix it.
I doubt they will be amenable to coming up with a new dynamic pricing algorithm.
