I think this Friedman quote still has relevance though:
Oh, I thought you were trying to build a canal. If it's jobs you want, then you should give these workers spoons, not shovels.
Does it really serve a purpose if you make it harder than it needs to be? And self-driving cars will be a benefit to everyone else. I can go down to the store and get a liter of milk for next to nothing because of milking robots and other automation, if I had to pay a living wage for someone to pull a cow's teats it would cost a *lot* more. All those stores who transport goods will get cheaper. The money people don't pay on taxis will be spent on other things. Everyone can spend their commute watching TV instead of wasting home time. It'll be more practical to live further from the office. Elderly might get around more and live more fulfilling lives. Large groups of people would have the benefits of a private driver, previously a rare luxury. In ways perhaps even better, since you get total discretion and it's always at your whim 24x7.
Assuming you can still find a job, of course. But we've been pretty inventive about creating new needs and services once we could afford to. The burger flipper might be on the way out, I doubt the chef is. A robot vacuum cleaner isn't scrubbing the bathroom or dusting the furniture. The electric lawn mower doesn't do flower beds or trimming the hedge. The washing machine doesn't pair my socks or iron my shirts. Of course you might say that one day we'll have a "I, Robot" assistant that'll do absolutely everything a human does cheaper and better but that's not in 10 or 50 years. Neither is self-repairing, self-replicating and self-evolving robots that work almost by themselves.
Real wages in the US has been flat for quite some time now, but at the same time you've had a massive influx of cheap labor on the global market depressing wages. You don't get a zillion Chinese or Indian employees working for a pittance anymore, when you look at the whole world workers are getting better paid. If it keeps going up, sooner or later it will return to growth in the US too because US wages are normal wages and not super expensive wages anymore. There is no magic that makes Americans stay far ahead of the pack forever, even though that how it's been in the past with the old world destrroying itself with world wars and an illiterate, primitive third world. There are smart people other places too, when they get the opportunity.
