Did you read the article?

Doesn't matter if you increase the number of crane operators loading trucks, because the trucks don't have enough container chassis, and - even if they do get a load - the warehouse isn't staffed to unload the container.

EVERY point in the system is broken. It isn't "there aren't enough trucks", it is, "faster shipping costs more, even if it isn't faster, and so there is no incentive for ANYONE in this pipeline to fix the problems at their point in the pipeline."

I actually work in the trucking industry, and am intimately involved with this.

The writer of this article has only barely scratched the surface of the problems. The issues extend back even to the manufacturers of the trucks themselves, who can't get the electronic parts they need to roll chassis off the production line.

The ENTIRE pipeline is about to collapse. And very soon (if not already) thieves will be working these overstocked container yards, opening containers, and stealing the contents for sale on the black market (aka Craigslist and FB Marketplace). And local police forces have ZERO capability to defend/protect these container yards, which may have three rent-a-cops making $38k/year wandering on foot around a yard the side of 30 football fields, stacked 3-8 stories high with containers. It'll be a criminals playground.
