Wenger's model, from World After Capital, holds that humanity has passed through a small number of transitions, each defined by which input was the binding constraint. Foragers were bound by how much food they could find. Around ten thousand years ago, agriculture shifted the constraint to arable land, and everything changed with it: migratory to sedentary living, flat tribal to hierarchical societies, animist to theistic religion. The Enlightenment and fossil energy shifted the constraint again to physical capital, and everything changed once more. The claim is that capital is no longer the binding constraint; human attention is. Because attention equals time plus intentionality, the question is not how many hours exist but what minds and bodies are doing in them. The practical consequence is that problems with no market price, such as climate, asteroid defence or fundamental research, are systematically starved and need non-market ways of pulling attention.
Origin
Developed by Albert Wenger in his book World After Capital and applied directly to Union Square Ventures' investment theses.
Core principles
- 01Every era has exactly one binding constraint, and almost everything else is organised around it.
- 02Technology relaxes the old constraint, which is what makes a new one binding.
- 03When the constraint moves, institutions built for the old one stop working.
- 04Attention, not capital, is the scarce input today.
- 05Attention is time plus intentionality, so where you point it is the actual decision.
How to run it
- 1
Identify the current binding constraint
Ask what the system genuinely runs out of first. For foragers it was food, for agrarian societies land, for the industrial age physical capital.
Pro tip The binding constraint is whatever everyone organises their status and incentives around.
- 2
Spot the technology that relaxed it
Look for the cluster of inventions that made the old scarce input abundant: planting and irrigation for food, dug-up energy and machines for land and labour, digital technology for capital.
Pro tip Inventions arrive in clusters, not singly; look for the bundle.
Watch out A single invention rarely shifts a constraint on its own.
- 3
Name the new scarcity
Whatever becomes the next bottleneck now governs the system. Wenger's claim is that with capital abundant, human attention is what is scarce.
Pro tip Test the claim by asking what money cannot buy fast enough.
- 4
Audit the institutions built for the old constraint
Incentive systems, religions, wage labour and market pricing were all built to mobilise effort under a previous scarcity. Ask which of them now misallocate the new scarce resource.
Pro tip Look for domains where results are so delayed that prices cannot signal effort well.
Watch out Do not read this as anti-market; Wenger is explicit that he is not anti-capitalist or degrowth.
- 5
Redirect attention deliberately
Treat attention allocation as the core decision, both personally and at the level of a society. Doom-scrolling and working on the climate crisis consume identical time but entirely different attention.
Pro tip Use the mathematics model: peer recognition, not price, can sustain enormous effort in the right domains.

Ask how violent the transition will be
Previous transitions ran over centuries or millennia and involved revolutions and world wars. Plan around which forcing events the current transition is likely to produce.
Pro tip Wenger's candidate for the current transition's violence is the climate crisis.
Watch out Assuming the transition will be smooth because recent decades were smooth is the failure of imagination he warns about.
In the wild
Wenger notes that moving from the agrarian to the industrial age did not abolish agriculture; everyone still eats food that is grown. What changed is how much human attention agriculture requires, falling to under two percent of the workforce in the United States. He proposes doing the same thing to market-based activity generally: compress it to roughly thirty percent of human attention and free the rest for work that cannot be priced.
→ The model reframes the goal as compressing the market sphere rather than abolishing it.
Roughly every million years the Earth is hit by something very large from space. There is no supply and demand for preventing it, so almost nobody works on it full time. Wenger uses this as the clean case of a problem that only gets solved if humanity decides to allocate attention to it outside the price system.
→ Illustrates why the attention-scarcity frame changes what deserves funding and effort.
Common mistakes
Treating the old scarcity as permanent
Malthus could not imagine the scientific breakthroughs that broke the land constraint. Assuming today's constraint is fixed produces exactly that class of error.
Confusing time with attention
Two hours scrolling and two hours working on a hard problem are the same time and completely different attention. Intentionality is the part that matters.
Assuming markets will price everything eventually
Some of the largest threats and opportunities have no supply and demand at all, so waiting for a price signal guarantees under-investment.
Is it for you?
Best for
Investors, founders and policymakers making decade-scale bets who need a frame for what changes next.
Not ideal for
Short-horizon tactical decisions where the constraint will not move during the holding period.
From the transcript
“every once in a while in humanity's history, we invent things that radically change what we as society have as a binding constraint on us”
“Then we went from land scarcity to capital scarcity, and now we're going from capital scarcity to attentional scarcity.”
“Attention is what was your mind and your body doing during those two hours?”
