I agree on one hand, but there's a lot of hand waving and hopeful/wishful thinking built into that answer.
It's very easy to say, "Do something else," but if it were that easy, it wouldn't be an issue in the first place. And if 20 million food service workers all get CS degrees, guess which will be the next industry with plummeting wages and few job opportunities?
We have more people on earth than ever before, but we also have more automation and less need for those people than ever before. It seems like at some point society is going to have some hard questions to answer about employment, pay, etc.
'cept with 20 million CS degrees, the software industry would boom - more code, more customized, bespoke software for every firm, presumably increasing productivity and output and thus, increases wealth.
Not to mention these people may also "stumble" upon something great by being entrepreneurial.
So it'd be strictly better to have 20 million CS degrees holders, vs 20 million hospitality workers.
If we “freed” people from work with welfare, 99.9% of recipients would smoke weed and watch cartoons, not create art. It might still be preferable to having people work low-engagement jobs, but let’s not be too idealistic.
FTR I also think the social safety net should be bare minimum existence, for a single person something like a bunk bed, 3 minimum nutrition meals (simple food like beans, rice etc not steaks...), clothes from a thrift store etc. -- It's more complex when kids are involved because you have to consider that you're essentially growing the future generation so have to consider the repercussions of underinvesting in formation.
This bare minimum would still leave lots to be desired and thusly incentivized (such as money for weed and a tv/netflix) ... But they'd have the time and basic support to do something contributing that only humans can do (at the moment at least) .
Example; There've been some pretty positive things happening around community gardens in some places (when they're not being attacked by self-appointed neighborhood Nannies that don't like to see people gathering together around something beneficial).
Example 2; I remember "maker" clubs and similar community groups doin' lots of really fun activities that benefited more than just the group itself (free community virus cleanups, operating system install parties, community LAN parties - everyone's welcome).
I'm sure that if enough positive activities were presented to society as a whole, you'd just naturally find a growing percentage of humanity doin' good things for each other that used to be considered "work" at some point in the past before whatever "safety net" made it unnecessary to do for survival's sake anymore. People might even still do some of those things at a higher level of quality than others and net themselves some personal gain out of it.
Problem is that humans aren't willing to cooperate with one another enough to even approach any sort of Utopian ideal, and they're often too ready to jump at all the reasons such a thing is "impossible" without being willing to even consider any ideas that might lead to it bein' a reality.
Instead of career tracks you will be offered volunteer tracks.
However, this is a complex solution to the problem and it is prone to being gutted because it will be seen as socialist and once there is full employment politicians will demand everyone to quit their clubs the same way they demand welfare recipients to quit today.
Yeah, that just took the wind outta my sails. I literally give up trying to restore my hopes for humanity or any sort of better future for myself or anyone else. We're all fucked. I need to just accept that.
The Restaurant workers had portable credit card stations to ensure they didn't have to run back and forth to a central register. The garbage trucks had automated arms for picking up trash bins. A busy restaurant had ~1/3rd the staff of a similar restaurant in the US. This compares to my condo association which recently hired snow shovelers who don't have a snow blower because they were cheaper than the ones with a snow blower!
There is no employment crises in Switzerland, and by simple inspection I'd believe that the American service/labor sector could absorb the 3-6x improvement in productivity present internationally without an existential crises.
The analog in software is working for a surveillance company versus architecting your software to cut out needless middlemen.
Which raises the question of why anyone would work, if doing whatever you want and still living a comfortable life was an option.
It sounds like a lovely future, but I don't the automation exists yet to replace all the jobs.
People with literally billions of dollars of wealth still devote time and energy to earning more. I don't think its a stretch to think that people who merely have enough for tolerable food, clothing, shelter will continue to do so.
If I look at the size of the median house, the price of the median car, that doesn't seem true. If most people would be satisfied with a basic income scheme and nothing more, why aren't most middle class people trying to save half their paycheck and retire before 50?
For a minimum wage worker it is absolutely trivial to see that the tradeoff isn't worth it and subsequently they behave predictably like a lazy person. People acting according to free market logic deserve the stick. Do you see the problem?
Let's say you got $20k/yr[0] for free. Do you think you could live comfortably on that? Would you be willing to work to improve your comfort level?
[0] full time US minimum wage with no time off is about $15k/yr
You work to be able to afford nicer clothes, more vidya games, fine whisky, more-comfortable retirement when you do stop working, vacations, better school for your kids, a nicer house with a view, and so on.
The carrot remains the same, the stick is just somewhat smaller.
I don't see anyone screaming about ditch digging jobs or dishwashers saying we should "save those jobs!" . Backhoes and automatic dishwashers have freed people from meaningless work. We should do the same for everything we can. There's a stereotype of struggling artists working at fast food/coffee shops, imagine how much better human life could be if we freed them to do their real work (the arts).
