I think the implication is that "six figures" ain't what it used to be. Even blue collar delivery drivers are making six figures now. So I take it the complaint is with the headline: "...even six-figure earners". The writer probably wants that to translate to "even doctors and lawyers!", but forgot that candy bars aren't $0.25 anymore, either. EDIT: though OP's linked comment indicates that my guess was wrong. Meh, my point stands: six figures ain't the "professional class" salary it used to be.
