Exponential growth can’t last forever, and I do worry about what will happen when the gravy train stops. Maybe we can figure out interstellar travel before it does so the limiting factor becomes “the galaxy” rather than “our planet”.

Not everything is in the exponential growth model. Most small businesses in your town for example. Margins might afford an upper middle class lifestyle for the owner and that is a good enough business model for this company to last decades, even pass down through the family.

Don't worry, private equity is working diligently to make sure that can't happen anymore.

On the micro level, I agree. On the macro level, I don't know how viable those businesses will be when the wider economy is no longer growing exponentially (and frankly that may well be the least of all concerns).

[asdff]

Well, they exist in places where the regional economy contracted significantly as well. They will be fine. They aren't so beholden to the wider economy as their customer base is local and they serve a need that has kept them in business for decades already, even with how many eras now of outsourcing and globalization and online shopping and all these other touted death blows that have been weathered all the same by these businesses.

> Well, they exist in places where the regional economy contracted significantly as well. They will be fine.

This is a non sequitur. If the economy contracts and 99% of these businesses go under, 1% may well remain (“they exist…”) but that does not mean that all is well (“they will be fine”).

> They aren't so beholden to the wider economy as their customer base is local

The local economy in most of America is highly coupled with larger corporations. Either the large corporations are the major employers or the large corporations are the major customers for the area’s employers. Even if it’s not that, everything is tightly coupled to the banking system, as we learned in 2008.

I think impending demographic collapse might give us a peek at that sooner than you'd think

[mplewis]

Clarify exactly what you mean by "demographic collapse."

> In the aftermath of World War I, birth rates in the United States and many European countries fell below replacement level. This prompted concern about population decline.[8] The recovery of the birth rate in most Western countries around 1940 that produced the "baby boom", with annual growth rates in the 1.0 – 1.5% range, and which peaked during the period 1962–1968 at 2.1% per year,[13] temporarily dispelled prior concerns about population decline, and the world was once again fearful of overpopulation. After 1968, the global population growth rate started a long decline. The Population Division of the United Nations Department of Economic and Social Affairs (UNDESA) has reported that in the year 2023 it had dropped to about 0.9%,[13] less than half of its peak between 1962 and 1968. Although still growing, the UN predicts that global population will level out around 2084,[81] and some sources predict the start of a decline before then.

In other words, the last time everyone got worked up over this, the trend reversed itself too hard within a few decades, and then reversed itself again. Meanwhile, over half a century after the "decline" started, we have over twice as many people as we had when it started, and the earliest projections for when growth will stop is another half century from now. I think there are a lot bigger problems we'll need to reckon with before then, and if we manage to remain stable by then, it seems like we have good precedent for reversing it fairly quickly.

I'm not so sure that global population growth tells the right story vis-à-vis declining birth rates in western countries.

[teiferer]

As long as everybody is nationalist (not to say racist) and keeps borders closed to protect the homeland, those differences matter. Realizing that one thing people get worked up about (immigration) is a solution to the other thing they get worked up about (not enough kids!!1) would be a great insight.

Well, they were directly asked what they meant and replied with a link to a giant Wikipedia article. If they had a more specific point to make, they're being weirdly cagey about it.
