With most salaried, white collar jobs your payscale is almost completely decoupled from your productivity. You are paid based on the market value of your skills and experience. You're essentially a commodity.
We see this in the software industry all the time: There's little salary difference between a "good" and "mediocre" programmer. The so-called "10x" engineer, myth or not, is likely to make just 10% more than their peers, if even that, not 1000% more.
