Scale Without Consolidation#

LA ties Boston and Amsterdam at 32 — but through a different model. Where Boston has institutional depth (universities, MassRobotics) and Amsterdam has intentional policy (broedplaatsen), LA has sheer scale: 72 library branches, 200K community college students, 5,000+ food trucks, 100+ 99-seat theater companies, and the Rose Bowl Flea Market (2,500 vendors).

The gap with NYC (38): density and transit. NYC’s participation infrastructure is subway-accessible. LA’s is spread across 500 square miles, car-dependent, and harder to access without a vehicle.
