That’ll be less painful if there are fewer people. Lower populations should lead to lower emissions growth too.
On the plus side, it will likely lead to lower emissions, assuming it doesn't lead to massive wars or other destructive behaviors due to the instability it will bring.
Of workers. Because retirement funds take money from workers to pay for retirees.
Assets and productivity, on the other hand, can grow a lot more than the population. Right now it's considered communism to tax assets. Once we get over that taboo things'll go a lot smoother.
what it means in practical terms is the destruction of the modern social safety net. some declining birth rates are ok but places like Japan, Spain, and South Korea look disastrous.
Does that sound like an extremely unlikely outcome? Back in 2008, we came within hours of credit cards stopping working. Projections say that if credit cards stop working, food distribution breaks down. Mass hunger is not far behind that. And there is nothing like mass hunger to destroy a society.
Esoteric problems in financial markets have real world consequences. We've gone nearly a century since the last real demonstration of that. Don't discount the possibility that the next demonstration will be within your lifetime. And in our more interconnected world, it's likely to be a lot worse.
We need universal childcare services, provided by the state and available to all, and other childcare-enabling reforms like automatic right to work from home and other flexible working arrangements for those with children.
These won't be popular with everyone, but you'll won't solve the demographic crisis without them.
Birth rates have been falling worldwide, regardless of the level of government support. It's much more a matter of attitudes about having children.
> The economic costs of having children at a replacement rate are simply too high
Nope. My wife and I have 4 children, on a lower-middle-class income in the US. Your lifestyle choices matter a lot. If you want to have children, you can find a way to afford them.
That is the story right there. We as a society spent decades upon decades demonizing having children at a young-ish age. "Your career is more important", they said. We got shows like "16 and Pregnant" to dissuade viewers from having children. People have become genuinely afraid of having kids.
Not until you are in your 30s does the social messaging shift from "only failures have children" to "why haven't you had a child yet?" That change in social pressure often compels one to start to change their mind, but at that point one becomes biologically limited in how many children they can reasonably birth.
That makes sense. I know that having less people is not a good thing, but I was brought up with the "impending population crisis" thing drilled into my head, so it's difficult for me to be alarmed.
I'm also all for getting women into parity with men. I know that there are a lot of men that will say that this is a bad thing, but I was raised amongst a lot of extremely capable women.
I feel that we need to support parents, if we want more kids. Right now, in the US, having kids is economically devastating, and there's almost no support from the government. I'll bet India is worse (but I could be wrong).
I feel that nature has controls built in. We see it all the time, in other species. I feel that if we drop too far down, the switch will be turned back on again.
[EDITED TO REMOVE TRIGGER WORDS]
You understand that your statement here is very racist? You basically dehumanize people you don't agree with and describe them as lower beings. Basically Untermenschen?
The latter part seems like the most meaningful cause world wide. Sex is a boredom activity and we just aren't bored in the slightest, ever. I think most married people know that long power outages are the most romantic thing that can happen (though, less now with cell phones).
I've theorize that they become overburdened by the pocket supercomputers that automatically start using it instead of local wifi.
Therefore my experience has been that cellphones tend to remain up, even though the power is down.
Pain for whom? The people profiting from cheap labor probably.
Why is such a massive sin to scale down? To slow down a bit, I don't think the whole world is about to collapse, but even if it was, I rather that than turning it all into the hellscapes we see on some of the most overpopulated places in the world just so a mere 1% of the population can indulge.
A pretty consistent trend throughout history is that shit rolls downhill.
"The poor will always pay for it" is a thought-terminating cliche that is often trotted out in support of the status quo (or some mythical past status quo).
How do you know that past status quo isn't actually worse for them than the direction things are trending? Do you we somehow stumbled upon some global maximum for them, and any deviation from that, in any direction is going to make things worse for them?
The Chinese have discovered that it is easy to crank down the fertility rate, but impossible to raise it again when you want to do that. And they have brutal totalitarianism on their side.
Kids are really expensive, and if you want people to willingly have them outside of accidents, you're going to need to pay them a lot of money.
My hypothesis is that as societies industrialize, they afford their population more and more activities that are simply more fun and rewarding than having children. So many people I know put off having children (or curtailed the number they had) because they were reluctant to give up the activities only available in a childfree/>1 child life. Ultimately, we are hedonistic creatures, and having kids is antithetical to the myriad hedonic pursuits available in wealthy, industrialized societies.

That's like, the complete opposite of the hedonistic young couple not using protection and accidentally getting pregnant.
These are all real examples of why people I know delayed having kids, curtailed the number they had, or never had them altogether.
It really makes you wonder if some actors would feel a need to exercise control over this scarce and limited resource...
https://ilsr.org/ is one resource, there are more.
(to your food example, the US harvests land the aggregate size of the state of Oregon just for biofuels, ethanol and biodiesel; this is, arguable, unnecessary, and there are many other examples of unnecessary economic activity that can be deprecated)
That said, like Democracy, capitalism is the worst economic system, except all of the others that have been tried. And there have been enough alternate experiments that I wouldn't want to literally bet my life on the next one working better.

(~71% of the world’s population now lives in countries with birth rates below the replacement level needed to maintain population size)
What’s stopping you from being a welder or dentist?
What’s stopping me? Probably some combo of wanting to one day afford a home and a family without having to move to Memphis and the a sense that I’d get bored as a welder and therefore be a bad one.
Man, septic pumper tho…
The last transition was British Empire to US and that was 1900-1945.
We can only hope for something better.
The result may not be extinction. But losing 90% of the human population won't feel that different if you're living through it.
A relevant book recommend, https://www.amazon.com/Collapse-Societies-Choose-Succeed-Rev.... It walks through a variety of past examples of human societies that went through this. There is no reason to believe that our current world-wide society will fare better.
That's not what's happening here. Birth rates are below 2.1 in many countries who are no where close to "outstripping their resources". There are other factors causing the contraction which have nothing to do with resource limitations.
In fact it seems like it's the opposite: richer nations with more resources tend to have lower birth rates. That's the scary part because it means there's no equilibrium to be reached. Birth rates could, in theory, remain low until humanity ceases to exist.
But realistically, I agree. Civilizational collapse would happen long before extinction, which seems like it would almost certainly return the birth rate back to pre-industrial levels. I just don't think that's a desirable outcome either.
Or, even more realistically, nations with state religions that effectively outlaw birth control and/or women's rights will take over the world, and nations which don't do those things will collapse. That also seems like a bad outcome to me.
Point is, I don't think it's wise to treat this like it's not a problem.
Schools is a good example, as there are less children, you need less schools and consolidate. So there are less jobs for teachers, now it looks like an equilibrium issue since over time it will balance out. But those teachers who are losing their jobs are adults, tax payers, consumers now and the loss of spending has a cascading effect.
What does this actually mean? Every time I try to wrap my head around why it's bad e.g. for a business to make a constant profit, rather than an increasing profit; or for the population to dip to some number and settle there, rather than increase; the explanations seem to become circular very quickly. I know it's partially my fault for not having a very strong economic education, but it also feels like something is fundamentally wrong with the theories - like they are making some underlying assumption about what is "good" that I don't share. But I can never seem to get down to it.
The only thing I understand is that as the ratio of old to young grows, more taxes are needed, of course. But that would only be painful during a significant rate of change, not after the number is stable, no? Is that really somehow apocalyptic?
I invest my wages to take advantage of compound interest. It’s kind of my only hope of having a family / owning a home / retiring. If stuff stops compounding, I’m fucked. Multiply by however many millions of people are on the same position.
I don’t necessarily think the theories are making any assumption about what is good (except for the “greed is good dicks”)but more acknowledging that this is how our system currently works and the first generation to step off this ride will have a horrible time.
When a certain region in a country gets a cluster of great companies or really any productive advantage you would want more buildings and people there. In a country with a growing population that would make most sense as you need to build houses regardless as there's more people entering the job market who need a home. In a country with a stagnant population for every home you build another needs to be abandoned. This is more expensive especially when this happens enough where a school in the 'abandoned town' closes and a new school should be made in the new town. You can see how the first is more efficient, you don't waste your fine buildings.
Because you're not "dwindling the population" in the way you think. You're not taking an "8 billion" number and changing it to "4 billion". You're taking this growing organism, and switching it into a shrinking mode. Worse, you're changing it to "shrinking mode" in a way where you can't switch it out of that mode. It will, by necessity, shrink to nothing.
And it shrinks quicker than you could imagine. When fertility rates are at 1.0 (China), each generation is one half the size of the previous. It doesn't seem like much has changed... there are 4 or so older generations that are still large (but non-reproductive). When you have a 0.5 fertility rate (South Korea), each generation is one quarter the size of the previous.
Human extinction only takes about 12-14 generations at that rate. Less than 350 years. Even before it gets that far though, things get awful really quickly. It's not as if it's 350 years, and then everyone's gone. Those last few generations have no technology, they're huddled around in the dark trying not to starve.
>If there's less population, we need less production and less workers.
This isn't as true as it sounds. Some of our technology does not scale downward. If you need a nuclear power plant, this has a minimum number of workers. Even if you only want half the power, you can't get away with "half the workers". So, as there's less population, some technology will have to be abandoned. If you just employ people at the power plant despite that, then you're by necessity pulling those people from some other industry... it's an opportunity cost thing, and you have fewer opportunities.
Sub-replacement fertility is human extinction. Not in 10,000 years, but in just a couple of centuries.
It's highly ironic to say "its dehumanizing!!" to say to a man that his treatment of women makes him a lesser being with the amount of abuse, neglect, and forced labor women are expected to take on by the men "dehumanized" here.
He's not even talking about race, so, not racist?
If you have backup power for your router and ONT/Modem, you should also still have internet service during a power outage. The ISP-owned ONT for a place I lived had a little lead-acid battery attached to it, and during power outages I still had internet service.
Hedonism has negative connotations, colloquially (and colloquially is how we are speaking).
