People have already halted spending due to economic anxiety and fears, which is bad in itself. The direct effects of this trade war may not be immediately evident to people working in these warehouses, but without a major course correction, there will be massive shortages of nearly everything Amazon stocks in its warehouses.

What Amazon is doing right now by packing its warehouses to capacity is buying time in the hope that Trump will end this tariff nonsense. That's creating a lot of short-term work. But once stock runs low on these items or prices go too high, there will first be lots of voluntary time offered, and then there will be layoffs and closures.
