Definitely true for sales folks at B2B companies- total comp can sometimes eclipse CEO when adding commission. My piece is focused on salary, not commission, cash bonus, and equity. Surely, a more complete picture of total comp is more valuable, but the scope of the piece was just focused on salary.
Then I think the article should explicitly point out that salary is only a piece (and perhaps not the largest piece) of total cash comp. Otherwise it is very misleading to the naive reader.
