Some of the above discussion has me feeling slightly less worried about the pains of population decline. It’s like the distinction that Marx thought communism would be possible after a certain baseline level of wealth was achieved, but the only countries to ever try it were
far below that level of prosperity, so what they were trying wasn’t communism at all, it was using centralized economic planning as a mode of economic development.
We’ve never seen population decline in a country with such abundant excess as many countries have today. Japan is probably our closest comparison, and they were much less rich when decline set in than the major developed economies of the world are today. While the Japanese people have certainly suffered due to the economic challenges of decline, and they are poorer in absolute terms than countries like the US, Japan is still chugging along quite well. No one would argue Japan is a basket case.
I suppose the Anglosphere countries are especially vulnerable to economic decline because of the unsustainable costs of suburban sprawl and car-dependent transportation networks. Denser infrastructure and other forms of transportation are just so much cheaper that it frees up a lot of a nation’s productivity to pay for rising healthcare and pension costs. And population decline might just solve that problem for us. At some level of population decline, we’ll decide that a federal bailout to repair a failing water system like Flint’s just isn’t worth it anymore.
This is really the long term implication of what Strong Towns talks about. We can prop up suburbia with wasteful spending when we’re so rich that we don’t even realize how rich we are. At some point though, the US, Canada, Australia, and New Zealand alike will very likely be dotted with abandoned suburbs. See:
”We Are All Detroit.
I think some people dismiss Strong Towns and Chuck Marohn as a lunatic doomsayer, but in the long run population decline will certainly prove his argument true. Maybe exurbs in the most desirable cities will thrive for centuries to come. But a lot more of this country will end up looking like Appalachia or the Rust Belt. The silver lining is that what’s left might end up looking a lot more like Europe or Japan. As mentioned in the Paige Saunders video I linked previously, Canada is way ahead of the US on proactively embracing urbanism. I also think New Zealand is getting more serious about urban infill than Australia is, but they’re still not embracing biking and transit nearly as much as Canada is.
