little to no capital investment over the last 20 years to increase intake capacity commensurate with demand. Welcome to the vampire economy:

What it will truly take to fix this problem is to run EVERYTHING 24/7: ports (both coastal and domestic),trucks, and warehouses. We need tens of thousands more chassis, and a much greater capacity in trucking.

This can only be fixed by either going full NAZI (which eventually fails anyways) or a crippling recession that crucifies demand. So guess which one we're getting.
