Note please that George is screwed whichever end of that thing he goes off of.
There's a lesson or two there.
In an interesting article at GoV, the discussion devolves to the ongoing attempt to sustain the Welfare State via Third World population importation, and the socially taboo alternative option of geronticide was the topic.
And then, in comments, it goes completely dipshitical, including the inevitable "Everything will be automated, and we'll all live in mud huts" codswallop.
I/we beat the robot-overlord automation nonsense to death with the arguments for/against self-driving cars (TL;DR: It ain't coming, sportsfans) both here and over at Silicon Graybeard's blog some months past, but for a refresher:
Dystopian nonsense, unconnected to reality.
Cars only cut the number of jobs for horsecrap shovelers, but the number of jobs from that tech upgrade increased for everything but horses, to the present day, for everything from car washers to road builders and street sweepers to oil drillers and refiners. In fact, there are now far more cars, trucks, and tractors than there ever were horses, by orders of magnitude. That's what technology does.
Computers and software magnify jobs, they don't decrease them, mainly because of GIGO problems.
Call me when software becomes flawless.
"Robots" may take away jobs from burger flippers, but only by increasing the jobs for those who load them with frozen patties and ketchup, service them, program them, repair them when they break, and design and rebuild their inevitable upgrades.
You're not going to replace people in most jobs, ever. You may change the nature of some jobs, but the idea that you're going to see whole swaths of the labor force displaced is rampant nonsense from watching too much Star Trek as if it were reality gospel, and doing too little actual work, let alone running an actual business.
And anyone who thinks AI will take over driving or airline piloting is ignoring the inevitable Hindenburg/Titanic moments that will get that nonsense cancelled in about a minute.
Those who disagree can show me their ticket stubs from the White Star Line or Greater Reich Graf Zeppelin Corp. for their last transatlantic crossing.
So tell me: did jetliners create less jobs than ocean crossings, or more?
And the reason you need so many drivers now is because shipping went from odd pieces to truck-borne cargo containers. The future of technology inevitably looks more like The Jetsons ("Jane, stop this crazy thing!") than it does or ever will Star Trek.
African countries have a pyramid, because there is no social security (except kids who will hopefully help support you in your dotage), coupled to a continent that whacks people with every natural and man-made population cull known to 10th century man, which is what most of that under-developed continent lives under to this day.
Dirt roads, mud huts, barbaric sanitation and lifestyle practices, and scads of helpful wildlife like lions and hippos, let alone malaria and Ebola, cull people even more ferociously than combining distilled alcohol with motor vehicles does hereabouts. Hence their demographic graphs.
(For a first-person explanation, read Kim DuToit's excellent 2002 missive: Let Africa Sink.)
The simple fix to the demographic "problem" is the obvious one, entirely overlooked in all of the above: what government cannot sustain (Social Security/Medicare) will implode and collapse.
What cannot continue, won't.
Once you don't have to worry about the nanny state's "safety net"/noose, demographics is irrelevant. Population at that point, like it has for time immemorial, will devolve to a question of how many kids, and thus mouths, you can support, and the life choices involved that each person makes. People who juggle lit road flares while standing in a vat of gasoline for a living won't, for instance, need to worry about a pension. Burn salve and bandages would be a better investment.
Anything else attempted is a race to becoming Zimbabwe, including the inevitable round-up and execution of the bureaucrats and dictator involved, and unless you re-introduce grizzly bears and wolves to NYFC's Central Park and the DC metro area, you can't get there and sustain it.
Importing the Third World to the West is merely a way to bootstrap draconian bloodbath wars between the current civilized populations, and the non-native invasive species.
All the present is, is a warm-up for that exact bloodbath.
Trying to extrapolate a future trend, without including the inevitable response to the current machinations, is a failure of reactive physics and sociology on a global scale, akin to suggesting that one could increase the zebra population of the veldt without the lions, leopards, and cheetahs paying the newcomers any mind or taking any action.
If you're rightfully worried that government immigration or healthcare policies don't have your best interests in mind (because they don't) the solution will be to take their choices away in both cases, not yours, and thus secure your borders, buy your own damned health insurance, and fund your own f**king retirement/pension, like you should have been doing since forever. The man who thinks he will sit in government's lap while it feeds him peeled grapes until he dies, wasn't paying attention in every history class since Socrates was teaching in Athens.
The simplest solution, in both cases, is to build a barrier wall from Brownsville to San Diego for the former, and one around the District of Columbia in the latter, and let no one from the other side get across in either instance, enforced with mines, machineguns, and flamethrowers a la Escape From New York.
If election to Mordor was a one-way terminal ride with no re-entry privileges, the enthusiasm for undertaking the trip would sufficiently fade to make further measures unnecessary, and the republic would look like Théoden's "after" picture once Saruman was dis-possessed.
Failing that, the increase of The Diversity and the impending financial collapse of the Nanny State should long ago have suggested to anyone with the wits the two most obvious conclusions:
Things are going to get sporty.
You don't have enough ammo.
