On an individual basis there are multiple portions of the economy for which wealth could be modeled or interpreted as a zero-sum game. Examples include landlord/renter relationships in high rent burden environments, or other segments where an individual is unlikely to ever be able to afford a "share of future economic growth" in order to fund retirement etc.
Lots of markets (most markets?) aren't growing at any particular moment. We should really figure out how to fix our system in the low-growth zero-sum regime because it's common and important.
In the United States, it's a different story. The tide is rising, but most boats have not been rising with the tides for about 40 years, and that's troubling.

The figure you linked does not indicate adjustment for inflation and does not segment expenditures by wealth, which is important, because the US economy as a whole is growing, but more than 100% of the growth is flowing to the top. The rich get richer, the poor (and middle class) get poorer. You have to segment by income to see this trend.
Inflation adjustments are tricky because it’s not really obvious how to measure inflation. But even adjusted for CPI inflation personal consumption expenditures have been steadily increasing in the 20th century: https://alfred.stlouisfed.org/series?seid=A794RX0Q048SBEA
Tangent 1: Placeholder: I don't agree that consumption metrics are better.
Tangent 2: Rich people do consume (colloquially speaking) proportionally to their increased wealth, but after sating their material desires they turn to financial assets: dibs on passive income and future growth. More for them does mean less for everyone else. Both in the first-order sense of owning more shares and in the second-order sense of being on the winning side of prevailing trends in globalization, automation, tax law, and corruption.
Jeff Bezos owning 10% of amazon does not place prohibitions on the amount of dollars you can spend.
Also, if Jeff's workers have more wealth, they don't have to spend a lot of their disposable income on paying student loans or mortgages, and they will have more money to buy more stuff.
There seems to be little correlation, much less causation, between the amount he pays his employees and the value of the firm in which he holds interest.

As a result of the above, the value of a natural resource changes over time. For example, natural resources used in electronics and batteries are relatively more expensive now than they were 100 years ago.
So, you can be technically correct by saying that wealth is zero-sum, but that's pretty much the same thing as saying "the world's 'wealth' traded for natural resources sums up to 100% of all natural resources"
It's the same with everything. When you're not at your limits of your ecosystem - things aren't zero sum. However once you do hit your limits, things become zero sum.
You even see this with businesses. Industries go through a growth phase. In the startup-growth-adoption phase, all businesses in that industry can grow. However, once market matures and reaches saturation, businesses struggle to grow or change. The only significant way mature businesses can grow larger at that point, is via mergers and acquisitions of other businesses.
A limit is a limit, doesn't matter if that's a demand limit, or a production limit, or a resource limit. The effect is still the same. Being under limits, makes things zero sum. If those limits were suddenly removed or increased temporarily, things would return to not being zero sum - at least until you hit another limit.
>It is rare that it means that not more can be produced.
In practicality sure. I'm sure we could make more basketballs than we do now. But physically speaking, you'd eventually hit limits. The earth is not infinite... we certainly could not make more basketballs than there is mass of earth itself. At which point we would either have to make new basketballs out of old basketballs, (zero sum), or raise our limits (mine matter out of other celestial bodies).
Why do you think so?
> In practicality sure.
And that is what matters? Why is it interesting that there is a theoretical limit on how many basketballs that is possible to produce with the resources available on Earth when no conceivable situation exists when that limit ever becomes relevant?
Someone should tell the record companies who say when you pirate a song, you're stealing from the artist who will not be properly compensated for the time they labored to write and record that song. I see corporate spokesmen expounding the labor theory of value all the time.
As far as LTV is concerned, we know it to be a flawed theory today because we understand the time value of money. LTV will hold in the long run with constant returns to scale. Without constant returns to scale, only the marginal consumer matters. In simpler terms, demand will affect price, not just supply. Now, if we make the errant assumption that the supply curve is completely flat in the long run, then LTV does in fact hold. That is, the LTV is not a terrible description of economic reality, as long as you note that a) an isomorphic argument can be made for “the land theory of value” or “capital theory of value”, so labor is in no way special, and b) LTV can only apply for goods with flat long-run supply curves. In any case, there’s a reason the early great economists used it! Smith, Ricardo, and others were not all idiots. However, today, we know better and it flies in the face of modern science and understanding to promote its use.
gdp (national wealth) is a made-up metric, it's aggregate, it's dynamic, incomplete relative to its stated rationale for existence, inapplicable to the discussion, and a whole host of other irrelevances to a real understanding of wealth and its distortions.
Look around where you live, at the things that you value. How many of them were created with human effort, versus just existed in nature? Look at everything from computer you're typing on to the chair that you're sitting in to the roof over your head. EVERYTHING that was created with human effort is an example of wealth creation.
Without dismissing your point, I would strongly push back against effort being synonymous with wealth creation. Having grown up in post-Communist Eastern Europe, there was no virtually correlation between the two.
The title "président des très riches" wasn't born out of nowhere, was it?
If he owned 9% instead of 10% and I owned the difference of 1%, then I would be better off.
P.S. He owns 11.1% and had more before his divorce.
