The article says they don't count because they aren't print journalists. Isn't that like a orchestra violist asking why top musicians aren't rich, but then saying Justin Timberlake and Rihanna don't count because they aren't orchestra musicians?
It seems like the big money in journalism is in video, not print. Just like the big money in music is in pop, not classical.
I suspect this is because it is easier for the casual viewer to quickly notice the difference between two people on screen compared to two people's writing. Being easier to recognize makes it easier to gain a following.
