That assumes everyone has a realistic view of their contribution. I've definitely worked with "10x" engineers, and also "0.1x" engineers, and a good share of the latter would be really offended if the pay was fair and they found out they are massively "underpaid". Some 0.1x engineers I worked with were literally playing fantasy baseball at work, those would be fine, but many (including confirmed ones whose messes I cleaned up) had outsized view of their contribution, and they would be very unhappy under pay transparency. Whereas I think the "10x" engineers would not be much happier knowing they are "overpaid" compared to most. So, this system benefits no one... it only works if workers are mostly interchangeable.
