Completely agree. Yes, great engineers tend to be compensated well, but only slightly more than the median performer. In other words, a 10x engineer isn't getting paid 10x more. It's probably more like 1.5x to 2x. If we somehow invent a magical way to track productivity numbers exactly, I suspect we'd see something closer to Price's Law [1] (Pareto distribution) which is essentially what this post is about, where something like 20% of workers contribute to 80% of the results. However, that doesn't means the other 80% is expendable which relates to your second point.

Paying what employees "earn" for the company is incompatible with our economic system where companies want to be profitable. Paying employees what they "deserve" based on contribution is probably also undesirable. I think you'd get the same income inequality dynamics but within companies. There is an averaging effect when you work at large corporations. That's either a good thing or a bad thing depending on the person. Individual contributions are averaged out, but so are responsibilities. I think Paul Graham articulated this wonderfully in his essay on what a job is and why some prefer to work for startups [2].
