The problem with this piece is that it assumes the labor theory of value. The "true salary" arguments don't tend to hold up well if you assume any other.
Or, to put it another way: does the value of a thing come from what the producer puts into it, or what the consumer gets out of it, or some other factor, or some kind of mix? The labor theory of value, and this "true salary" argument, are absolutist in that they depend on value coming solely from the first: even attempting some kind of blend or balance between multiple factors causes serious problems.
