@tylercowen + stimmie demand - UI labor = too much stuff trying to fit through too little logistics capacity, with feedback ripples of disruption caused by the pinch points.
@tylercowen Capacity slow to increase because: big lumpy investments need long-term use to be profitable, inflexible union labor contracts & uncertainty abt '22, long lead time for new equipment (esp bec chip shortage), and lots of govt dependencies (env/land use, customs, rail regs)
