The mechanism is the economics of upper-tier capability development. Judgment, taste, strategic intelligence require time, mentoring, and institutional support to develop — resources available to those who already occupy positions of sufficient economic security to invest in long-term capability development, and unavailable to those whose economic position requires the continuous production of saleable output.
The stratification is different in kind from the conservation-phase division between specialists and generalists. It is a division between those who judge and those who execute — a division with different political implications because it concentrates the capacity to shape outcomes among those already positioned to shape them.
The democratization of capability, which You On AI celebrates, is real. Anyone with AI tools can produce competent output. But competent output is not excellent output, and if the capacity to produce excellent output remains concentrated among a small population, democratization of production may coexist with stratification of value. Everyone can build. Only some can build well. The premium accrues entirely to those who build well.
Prevention requires public investment in judgment development that is available independent of economic position — the educational, institutional, and cultural infrastructure that treats depth not as a private luxury but as a public good.
Described in On AI as one of three candidate basins for the AI reorganization, extending analyses of stratification dynamics in prior technology transitions.
Two tiers. A small judgment tier, a large execution tier, with limited mobility between them.
Economic gatekeeping. Upper-tier capacities require resources unavailable to those most dependent on lower-tier income.
Democratization plus stratification. Production becomes universal; value remains concentrated.
