The structural changes elsewhere in the corpus are pulled by a common economic engine: **the collapse of the billable-hour / leverage model and the rising cost of capital.**

A044 and A045 attack the revenue model directly. When AI compresses billable junior hours, the [[prereq-billable-hour-model|hourly model]] is structurally threatened ([[claim-billable-hour-obsolescence]]), so firms must move to [[concept-value-based-pricing]], [[concept-unbundled-services-delegation]] ([[action-shift-pricing-model]]) and redesign compensation away from headcount ([[action-redesign-compensation]]). The obelisk's whole logic is *leverage redefined* — from human hierarchy to AI infrastructure.

A049 adds the macro squeeze: the [[concept-end-of-cheap-capital]] — driven partly by AI infrastructure spend itself ([[claim-ai-drives-interest-rates]], [[contrarian-ai-capital-scarcity]]) — forces [[concept-value-based-management]] and rigorous allocation ([[framework-capital-allocation-constrained-world]], [[claim-wacc-historical-norms]]).

**The synthesis:** professional-services firms face a double compression — AI shrinks the hours they can bill *and* capital gets more expensive at the same time — which is why "redesign, don't bolt on" ([[quote-bolting-on-ai]]) is framed as survival, not optimization. The broader macro frame is [[cross-macro-forces-reshaping-talent]].
