Good discussion. It gets to increasing levels of complexity as we move further down this rabbit hole, so I'll try to limit myself to one more lengthy response.
At the basis of your argument lies the assertion that at some point, whole swaths of society will have literally nothing to sell, particularly their labor, no matter what they do to change that. No retraining will acclimate them to the new situation.
First, I have a hard time accepting this. We've never once in our history come up against such a problem, despite the steady march of technology. I don't accept that technology destroys net jobs. It moves jobs out of one sector where they are no longer needed and into another where they are. One would think that if this were true, then as not only the population increased but technology advanced, we'd be seeing a steady increase in the unemployment numbers commensurate with technological advancement.
What you're arguing here is essentially the faith based assumption that things fundamentally do not change. If we didn't have a problem in the past, we won't have it in the future. Vague assumptions that things will just automatically and organically shift around to compensate is not an adequate approach to analyzing the issue I've raised. You have to understand WHY we've been able to compensate for the jobs killed by technology in the past in order to project whether we will continue to compensate in the future.
That improving technology will continue to kill jobs, particularly blue collar jobs, indefinitely into the future isn't really debatable. What IS debatable is 1) the time frame, i.e. how quickly does the technology progress, and 2) to what extent will our economy compensate the way it has in the past. The first of these is pointless to debate here because neither of us knows how fast it will progress. That's a subject for futurists who are often wrong anyway. The second point, however, which is the main objection you raise to my argument, is something we can meaningfully discuss.
In the United States, we have seen a historic shift in jobs from blue collar to white collar over the past 100 years. That much is plain historic fact. The specific mechanism is broadly this: 1) technology is introduced which reduces the need for physical human labor; 2) this then decreases the costs of goods which in turn, 3) increases demand causing economic growth which in turn, 4) creates more jobs.
It's a feedback loop. It isn't infinite, however, for the following reason. Much of the money freed up by cheaper goods has gone to the services sector. People can now better afford doctors, lawyers, accountants, money managers, and other highly paid service professionals. We in turn have successfully expanded our educational infrastructure to accommodate this growing demand: more colleges and universities, expanding the capacity of existing ones, and providing government backed student loans. So while the blue collar sector shrinks, the white collar sector expands, and since those jobs pay better, we now have higher wages AND cheaper goods. There is no doubt that technology has greatly improved our standard of living, particularly throughout the 20th century.
But we're reaching the limit of this compensating mechanism, for reasons I've explained in my posts above. Conservatives in particular are starting to make the following rather accurate observation: liberals want everyone to go into higher education (because they see the technological future as demanding it), and hence they want to provide loans for everyone to do so, yet we're starting to push people into it who do not belong there. The ugly truth is that there are differences in genetic intelligence among human beings. The argument is that if we keep loaning more and more people money to go to college, many of these unqualified people will either flunk out, or barely get by, but end up working low paying jobs which do not require the education they received, then defaulting on said loans, bursting this "education bubble."
While I'm skeptical that education is a bubble that will burst, because I see some differences between the situation with the housing market and student loans, I do agree with the premise that we're reaching the ceiling percentage of the population able to be trained for brain intensive work. The liberals correctly observe that technology creates the need for a more and more educated populace, but the conservatives correctly observe that genetic limits put a cap on how much of this we can accomplish, and that we're now showing signs of reaching or even exceeding that cap. Yet this is the very compensating mechanism that has offset the job elimination caused by automation. So we're reaching an impasse.
There's already evidence of this as an economic trend. In a global recession, corporations lay people off to cut costs, and in a particularly severe one, they are cautious in how they increase production once the recovery is underway and demand starts to perk back up. They can either a) hire back the expensive American workers, b) offshore to countries with cheaper labor, or c) invest capital in machinery to replace human workers. During the recession, off-shoring has continued apace or slightly diminished, while capital investment in machinery has reached all time highs, and the economy is adding jobs but at a lower pace than the amount of economic growth suggests it should.

Many economists believe we are headed for higher structural unemployment in the longer term, and I agree with them. This recession has simply accelerated an existing trend. Some of it is off-shoring, but off-shoring is a problem that naturally diminishes over time as the developing world improves its standard of living, which is happening year by year. Automation will not stop killing jobs, and absent a populace with genetically boosted intelligence, we can't compensate for it to the same extent that we used to.
Furthermore, there's a market for what people want. Not everyone wants to be waited on by a machine. A Winn-Dixie near where I live had automated checkouts. Now they don't. Turns out they weren't cost effective because people were only using them as a last resort, which put pressure on the human cashiers, which pushed the company to hire more humans and remove the automated checkouts. I don't know if that's a larger trend, but to say that absolute domination by machines of sectors which require menial labor is inexorably our future is not necessarily certain.
You're missing the point of automated checkout. It isn't about what the customer wants. It's about saving on labor costs. Both major super-market chains (Safeway and Albertsons) here in CA adopted these about 3 years ago. Started with 2, then 4, now 6 machines per store, with the human checkers progressively disappearing. And what's happening is that people prefer to have someone else do the checkout for them but there are fewer people to do it, so the lines at the human checkout stands are longer, causing people to go to the machines which had no lines. Now the machines are getting lines which are shorter than the human checkout lines, but lines nonetheless. Bottom line is that it's inevitable and the consumer will go along with it because it means the food is cheaper.
It's like the old full serve vs. self-serve gasoline. Full serve was nice and everyone would take it if it didn't cost more, but it does and now it's largely a thing of the past. Same thing is starting to happen with retail checkout, and it will continue to progress nationally even if it appears in fits and starts in certain stores or locales, because the technology only gets cheaper and better.
Secondly, your scenario is so broad as to be almost unanswerable. You're making predictions about something we have no reason to suspect is even 200 years away. People thought in the 20's that by now we'd be on other planets. We don't even have flying cars yet.
No, my predictions are grounded in present day reality. This isn't Ray Kurzweil opining that we'll have strong AI which will take over for humans even in brain intensive tasks by 2045. I discount that as too speculative and probably too far off to bother considering right now. What I'm talking about is what has already been happening: replacement of physical human labor by machines, and also certain limited forms of non-physical labor by computers (customer service comes to mind.) It's already happening and there is zero reason to believe it will not continue to progress. The exact pace of it is debatable, but we aren't talking about when we reach a theoretical end state because the problem I identify gradually increases by degrees as time goes by.
To expect an answer to a scenario which due to its remoteness and vagueness you can tailor to frustrate any argument against it, is kind of unfair. It's unfair to assume that the world will change so much, yet people don't change with it; the kind of technological advance you're talking about doesn't happen overnight. Is it not possible that people will adapt as technology adapts?
If you believe Kurzweil, it's possible that humans will have cybernetically and/or genetically enhanced intelligence which could solve the problem I identify above, but then he also believes that AI's will take over the jobs that require intelligence. The bottom line is that the problem I am discussing is grounded in what's already happened and continuing to happen, while these solutions are more in the realm of science fiction and likely further off.
Third, and as corollary to the second point, your scenario packages within it the challenge not only to solve future poverty as a result of whatever development, but also simply to solve poverty in general: The conditions you're talking about, (people being permanently unable to find a job), exist already. No one is against safety nets for those who are truly disabled, but despite safety nets, despite any human attempt to solve it, poverty will be with us. Someone even in the best and most humane society will suffer for lack of food or water.
I take it for granted that there will always be non-zero poverty. I think technology can diminish it to near zero by making goods so cheap as to be virtually free, but we need new economic and political paradigms to accommodate the future that technology is leading us toward.
The economy is not some entity that we bend to our will. It's not an entity in the first place. We make the economy. It is the sum total of our trade. I suppose that is why I don't understand your scenario at a fundamental level. You seem to view the economy as a horse, and people as riders of it in a rodeo. To me, it's just what I buy and sell.
Curiously, your first sentence undermines the argument you make in the rest of the paragraph. In any event, I do think we can exercise control over the economy, but we may need some paradigm shifting because we are facing material realities that make existing paradigms outmoded. I believe the free market will likely continue indefinitely, yet the argument that we should limit the safety net because it breeds laziness and people should "pull themselves up by their bootstraps," problematic today because we already have permanent structural unemployment in this country, is going to become increasingly absurd as its moral underpinning continues to wither away as technology progressively creates higher and higher structural unemployment. To the contrary of what conservatives today desire, we're going to need a greatly expanded social safety net, not a diminished one.
