When this applies
when predicting the behavior of a population of future agents whose composition will be shaped by selection pressure
The takeaway
In a system with reproduction/compounding dynamics, the long-run composition of the population is dominated by whichever behavioral type grows/compounds fastest, not by whichever type is currently modal — but check for 'dissipation shocks' that interrupt compounding (death, succession, satiation) before concluding dominance is inevitable.
Why it works
Just as biological evolution selected human drives because those traits propagated, economic/competitive selection will favor firms or individuals who reinvest/accumulate rather than consume, because such agents grow faster and come to dominate resource share over time — UNLESS a dissipation shock (inheritance to poor stewards, philanthropic giving, death) interrupts the compounding.
One level up
To predict a population's long-run character, identify the trait with the highest compounding/reproduction rate and ask what prevents it from already dominating historically.
Where it stops holding
This stops working when dissipation shocks (death, bad heirs, satiation, philanthropy) reliably interrupt compounding before it concentrates power — as the historical case of titans of industry suggests has repeatedly happened.
Detail
approach: Apply selection logic: does the trait in question (unsatiated capital accumulation) compound faster than competing traits (consumption-satisfied wealth)? If so, ask what historically interrupts its dominance (dissipation shocks like inheritance, death, philanthropy) and whether those interruptions will persist (e.g., will radically extended lifespans or better-aligned trusts remove the interruption)?
signals:- Historical titans of industry eventually gave wealth to heirs/foundations rather than compounding indefinitely
- satiation in capital lowers investment incentive and raises consumption
- immortality or perfectly aligned trusts could remove the traditional dissipation shock
rationale: Phil and Alex agree the accumulation-preferring minority could in principle dominate if dissipation shocks disappear (e.g., due to life extension or well-designed trusts), but historically this hasn't happened because of succession/satiation effects.
In their words
And maybe just based on that, you can make some predictions about what their preferences will be, but it is the kind of entity which prefers to have human intrinsic goods going to be the kind of entity that accumulates resources the most? Probably not, right?
