US economic reports present a puzzle: GDP grew at 4.3% in Q3 2025, the fastest in two years, yet unemployment rose to 4.6% with stagnant payroll growth. Three interpretations exist: GDP is overstated and will be revised down; labor data is misleading and the market is healthier than reported; or robust GDP growth is driven by a productivity surge, particularly in tech infrastructure, where compute substitutes for labor, contributing significantly to output with minimal job creation.
