The mean wage for a particular job role centers around its contribution to production. There are LOADS of extenuating variables which affect that mean, so it’s not a tight correlation. But ultimately, wage is highly affected by contribution to GDP.
It’s NEVER about how hard a job is to do, rightly or wrongly.
Service sector jobs don’t contribute at the same rate as manufacturing sector. They fit into the scale much closer to retail.
So, you can bemoan what service sector growth does to the overall society all you like……..there’s no real solution to it. Historically, when government has muddled with wage controls over and above simplistic “minimum wage”, the economy suffers — — badly.
A couple of other thoughts:
“Seriously, a robot can barely be taught to fold a towel, “
Actually, they’re pretty good at it. It’s just a matter of justifying the cost.
“let alone clean an entire hotel room”
Probably not, but robotics can make the job easier (already have, in the form of these things we call “vacuums”) and therefore require less staffing.
“deliver food through a drive-thru.”
Yes. Already happening.
“And really, have you priced out a kiosk lately? “
My dear, have you seen the thing called an “ATM?” It’s much more complicated than than a fast food ordering kiosk, and they have replaced tens of thousands of tellers worldwide. In Europe, I’ve ordered food in restaurants using a cheap tablet attached to the table; the entire Chili’s chain has gotten rid of thousands of waitstaff using them.
”This robots-will-replace-you-all threat is simply not based in fact.”
I suggest you look around you. It’s happening.
