I think you misunderstood me a bit. This guy is totally right that the jam is in waiting for trucks to get in and load. The truckers and the warehouse workers are getting under paid due to all the flow problems. But… If the trucks are waiting, then there are enough trucks. If the cranes were running but waiting for trucks that would be a truck shortage. Since there are a bunch of extra trucks waiting there bottleneck is elsewhere. If you threw more trucks at the problem it would just make the lines longer. In a perfect world the number of trucks would actually stink down to just enough that there was barely any wait at all because that’s all the port can handle. The above model is of course overly simple, all trucks are not the same, some might be able to load right away and some might take forever to get the right container. But this guys report seems to indicate that the bottle neck is port side
