I agree, but rankings are by their very nature zero sum. If one person goes up, another goes down unless they are exactly equal. That level of equality is something I think impossible to achieve and even if we did, humans would find some other way to rank people. But compared to the past, we can make it better. There is no reason why the 50th percentile today cannot be equal to the 60th percentile of yesteryear.
