The article says that "top job" is sensitive to the specialization or lack thereof with the job title. Secretary and Truck Driver appear high because those titles apply across all industries. There may be more software developers than these jobs, but they're delineated into things like Financial Architect, Avionics Developer, Educational Software Engineer, Medical Analyst and so on. There's also seniority modifiers for these jobs, but nobody talks about a Principal Secretary or Resident Truck Intern, so the base forms appear more populous.
