Steve Sailer mentioned this a while ago in passing–personal assistants are the new butlers to the progressive elite that’d be ashamed to go for the real deal. Like a majordomo these assistants render personal services and delegate menial tasks to the real new servant class, say Mexican pool boys or Ukrainian nannies. US elites eschew the traditional black servant nowadays, blacks resenting such jobs increasingly as being a reminder of past days of shame, their mostly non-black non-employers feeling something similar, though not exactly the same. Black crime rates aren’t lost on them, not at all, though being studiously ignored publicly. The likes of Steve Jobs or Madonna have (or did have) a tendency to work those horses, they don’t want to get too attached, and they wouldn’t want them to get too attached to their jobs.
