At the limit, not growing the productive population puts younger generations in a position of existing solely for the purpose of serving the non-productive population. At some point, they will simply choose to opt out and the whole thing collapses.
Also an economy that requires an infinitely growing population feels like a pyramid scheme which is also an unsustainable system.
Or not. It could be oscillatory and humanity could cyclically reverse-decimate itself while the descendants of the survivors get to enjoy millennia of the fun part of the pyramid scheme.
The big losers are whoever is part of the "perish in a holocaust" generations, and probably the first couple bootstrapper generations afterwards.
Only if we don't explore and colonize the stars. From what we know, the universe is infinite.
And, before you suggest it, no, there will never be faster-than-light travel, and even relativistic travel is super unlikely.
But productivity for productive people is increasing. Is there an assumption that retiree spending is also going to increase to match?
Realistic solutions look something like: - we increase productivity of the working population - we lock or decrease the per-year, per-person spending on retirees - we decrease the % of their lives that people spend retired
Economic growth is the result of productivity, which is the product of the number of people working, times their per-capita productivity. If each successive generation is more productive per capita than the last, then each generation can support successively more non-productive people.
But future generations won’t need to support as many non-productive people as we do now, because the Baby Boom will die off. In the U.S., the peak of non-productive populace is only the next decade or so.
for a contrast, look at South Korea - https://www.populationpyramid.net/republic-of-korea/2025/
That tells a quite grim story, with an outcome thats totally inevitable but will take 20 years to play out. the die is already cast, and I cant see how the country survives.
The fact that they do this coercive paternalism on the very platforms that substitute for real life social interaction is very rich to me. I'll listen to them when they divest from the social corrosion machines.
I don't think anyone enjoys them per se.
People don't gloat at privatization but aforementioned wealthier retirees rely on corporations squeezing ever more money out of customers, employees, and vendors.
Growth isn't sustainable, of course. If you're a gardener you get to experience the joy of growth every year, but you have to "pay it back" in autumn and winter as everything dies back and resets. The seasons force it on you in the garden, but we can't force it on ourselves. We'll just keep having summer after summer until it all goes boom.
On a personal level it might be possible to "bring winter back" - I'll have think on what that might mean.
A pyramid inversion means the old keep voting for OPM from the young, using their numbers to crush them, meanwhile there are fewer and fewer young to actually pay it. Eventually creating instability, couple this with entitlement "I paid that dead guy, so that kid owes me!" (of course, abstracted, as "the government owes me" to hide the kinetics) and you are in a bad spot.

yes under any system youth are needed. But SS creates a tragedy of the commons. Because retired get benefit obligation of children whether they have/adopt/foster the children or not. In most other systems, the link is more direct, so there is greater incentive to have or adopt child and provide investment in the child, as their success is directly linked to yours. In SS system you can reneg on most of the responsibility of creating the engines of the next generation but still simply scalp that investment off someone else, and indeed still get roughly the same share without making the investment. Obviously there is great moral hazard to simply scalp the benefit of children without having to make the investment yourself, and SS is all to happy to provide that.
a) make younger female family members do all the work
b) make them invisible, politically and socially, so everything looks fine
They might not have GDP-increasing jobs that show up on balance sheets, but grandma watches the kids (effectively working as daycare, off-books), grandpa fixes things, and so on.
By demanding everything be reduced to the nuclear family (or smaller) we've created an unnatural situation on never seen before on a global scale.
Yes I believe this brings up one of the more poisonous elements of social security, even if it is worth it. It completely decouples the mutual assistance where the parent and grandparent form a symbiotic relationship in the interest of raising the child. Instead of a quid-pro-quo, the government violently enforces a one-way transaction and the older generation can simply tell the younger generation to kick rocks.
Obviously I don't think the elderly have any responsibility to do daycare or fix things, but the fact they can simply not do so while demanding the counterparty still keep up their end of the bargain -- has consequences. If the older generation can tell the younger generation to kick rocks, then the younger generation ought to be able to tell the older generation they can kick rocks back to whatever private savings/investment they have.
Of course, many actual families do NOT go to extremes, and in fact USE the social security they get to help fund the grandchildren, in all sorts of ways. But you have to actively fight against the status quo to do so.
It's interesting to note that even though everyone 'knows' you don't pay SS payments into some account somewhere that is drawn from later, it's transfer payments now - it is still marketed and sold as the former.
Now perhaps 401ks owning stocks is effectively "lending" capital to the working-class for a fee - but you'd have to argue that.
Wages are constrained by the number of workers. Capital is constrained by total productivity.
I'm not sure what the state of the art is with either of these, but I'm now imagining scaled-up Roombas stealthily cleaning the streets at night.

More seriously, I think there is a before-and-after point with AI, before some point the automation is just a "normal technology" and we need humans for a lot of jobs, pensioners can only get meaningful pensions when a new generation is present to pay for it all, otherwise pension ages need to keep rising; after that point, automation is so good we can do UBI (AKA "set the pension age to birth")… well, provided the state owns the automation, otherwise good luck demanding free access.
People say "Oh, but GDP isn't everything" - but it's correlated with almost everything good, so might as well be.
Sounds lazy to me
How do you know if an organism is thriving in its environment? You count the offspring over generations.
we have a diseased misanthropic culture. i dont know where it came from but its existential.
Declining populations are trickier for most economic concepts though. Less labor, less consumption. That said, a slight decline can leave more houses unoccupied which can be good. A major decline would mean so many unoccupied houses that you would have broken and abandoned houses though because it would be too costly to deal with the abandoned units.
This has nothing to do with capitalism; it's a resource allocation problem. We spend inordinate amounts of money on end of life care, and any changes are currently unacceptable to voters.
You can imagine a steady-state population where the age structure is stable and productivity is high enough to sustain the retirees, trainees, and disabled.
