I suspect that the old practice of wealthy families employing full-time household servants will make a significant comeback over the next couple of decades, when legions of low-skill but able-bodied people find themselves irresistibly replaced by software and robotics. Sure, there'll be crying and grumbling over having to take jobs that many folks today consider to be beneath them, but personal servants for the rich were the norm for much of human history after the rise of agriculture and cities. Social expectations shifted during the Industrial Revolution and will shift again with the Robotics Revolution.
It also seems likely that that skillfully created handmade items such as fine furniture will see wider adoption among the upper crust as their wealth relentlessly increases, leading to steady employment for craftsmen in hundreds of thousands of small boutique shops. This is a historical norm as well although the scale will be larger. The rapidly advancing state of the art in low-cost but capable computer-controlled home milling machines and 3D printers obviously will help fuel this trend. In a side note, I suppose that using automated tools kind of blurs the definition of "handmade," but c'est la vie.
Likewise, personal services should see a continuing rise in popularity -- in-home pedicures, manicures, massages, and haircuts as well as expert home cooking by visiting chefs and so forth. In particular, cooking well is a wildly popular skill, and most otherwise low-skilled folks undoubtedly could pick up the knack if motivated. Really, this all happening already, but the pace should pick up quite a bit once robot-driven mass unemployment becomes a thing. Technology leads to fun possibilities -- for example, it's easy to visualize a lumbering beast of a food truck that hosts expert chefs who prepare custom orders for delivery within a limited service area around the truck by small, speedy delivery robots. Needless to say, said food truck bristles with touch screens that display a steady stream of orders from cellphone apps that also provide continuously updated GPS coordinates for the delivery robots. "Hey, Bob -- looks like your Maine lobster with lemon butter is here. I see the food truck bot coming from that corner."
The basic idea is that wealth always, always seeks avenues for spending. Few people indeed gather paper riches merely for the sake of giggling behind closed curtains over their bank balances. Admittedly, a lopsided distribution of wealth will kind of suck for those at the bottom, but outside of the true unfortunates who live on the streets, the bottom class will still be richer than kings were a thousand years ago. Who among us in the developed world doesn't have a cellphone, a color television, and access to enough cheap food to grow mightily into a fat boy or "woman of considerable girth"? Moreover, depending on political winds, a future United States might indeed see a universal basic income that very effectively persuades the have-littles from ever seriously contemplating revolution. I don't imagine the upper-crust types will squawk too much about the huge cost of such social bribery as long as they can keep tootling around in their auto-piloted Rolls-Royces and sipping their top-shelf boutique wines with Beluga caviar while smiling servants buff their toenails. That's the beauty of the increasingly automated production of wealth -- buying off the peasants becomes more and more affordable for the have-alls, and unlike ancient Rome, there aren't any Visigoths hammering on the gates.
