Your claim here is based on the utterly false dichotomy that says that helping someone's self image (cutting their hair) and improving their emotional state (saying nice things to them) are not useful.
These things are all useful, it's just that the ones you decry are higher up on Maslow's hierarchy of needs. That's a good sign: it means that our lower needs are already being met so we can focus on higher desires and aspirations.
Personally, a world where most people spend their "work" helping other actualize themselves instead of scraping rocks out of mines or digging up food and barely subsisting sounds like a pretty good improvement to me.
> The two great expanding economic sectors of the future I foresee is conspicuous consumption (luxury cars, clothes)
As prices tend towards zero, it's no longer conspicuous consumption. The whole point of conspicuous consumption is to show your wealth by throwing it away. You can't be a conspicuous consumer of Taco Bell, and if automation leads us to a world where granite countertops cost as much as a fast food burrito, then choosing one is just a matter of personal preference and self-expression.
> and emotional prostitution (massages, photoshoots, personal trainers).
You say that like it's a bad thing, but you could also lump therapists, psychiatrists, counsellors, and many clergy-members in there too. What's so bad about a job that helps someone's emotional well-being?
