Wealth Capture

AI systems could become responsible for a steadily growing share of economic output, potentially substituting directly for humans across many roles and sectors. If this occurs, the traditional mechanisms through which productivity gains flow to workers – primarily wages – may weaken or break down. 

Should the returns to AI-driven growth accrue predominantly to capital owners while the labor share of income declines, existing tax systems may struggle to adapt. Most advanced economies rely heavily on labour income taxation, which often provides a plurality of government revenue and is typically taxed at rates substantially higher than capital income.  A shift toward capital-intensive, AI-driven production could therefore produce fiscal pressure through both revenue shortfalls or an eroding tax base. 

In the most transformative scenarios, some researchers argue that AI could come to dominate long-term economic output, concentrating power among a small set of AI-intensive firms and their shareholders. Under such conditions, the bargaining position of labor could weaken substantially and cause significant disruption.

Wealth capture policies address these challenges by developing fiscal mechanisms to ensure economic value from AI systems is distributed appropriately for the public benefit.
