I honestly can't find exactly what jobs are being killed. What jobs exactly are even considered middle class seems to be highly contentious and subjective.
Can anyone point out to me an exact list of which jobs are reducing by technology? I, personally, don't consider a manufacturing job to be middle class, for example. And, it would seem, neither does wikipedia: "The following is a list of occupations one might expect to find among this class: Accountants, Professors (Post-secondary educators), Physicians, Engineers, Lawyers, Architects, Journalists, Mid-level corporate managers, Writers, Economists, Political Scientists, Urban planners, Financial managers, High school teachers, Registered Nurses (RNs), Pharmacists and analysts, etc...[8][34]".
