I could definitely see the lower class being more than grumpy about drones stealing their jobs, especially after hearing people around here gripe about illegals taking all the jobs. Of course, unlike the jobs here, the drones would be taking jobs that the lower class want to do. (Here most of the illegals are doing jobs that the average person will go on welfare before taking: Roofing, Welding Train Cars, Picking Rice, ect.)
You also can't forget the age old standards that require a human touch: Escorts, Strippers, Artists, Musicians, Trid Directors, ect.
