Agreed 100%. Our (informal) manual for consultants used to say something like
"The cupcakes in the break room are not for you. Most people will not care if you take a cupcake, but somebody will, and we will hear about it. We give you money instead, and we will certainly bring you a cupcake if you want one."
FWIW, this isn't the case at Google (or many other large technology companies). Google dictates the staffing agency markup (which is very limited) and audits for compliance.
This, among many other processes, has significant negative impacts on the quality of the agency that will work with Google on this sort of work - but it does help with cost control.
(Source: I ran one of these agencies, and Google was a past client.)
It's answered (I believe) right below the chart: "Importantly, the data does not solely include TEUs arriving in a particular week. It also includes TEUs arriving in prior weeks that the port expects to handle in the stated week."
In other words, it includes the backlog that's building up. "Expects to handle" isn't the same as "can handle." That's going to go up until the backlog is cleared.
(There is data that could prove me right or wrong, but the article doesn't provide it.)
Based on the most active thread here, I think this article has accomplished its goal, which is to lead (smart) casual readers to believe that the congestion and associated delay are due to increased exports to the US because of the predicted increase in consumer spending. (This is a trade publication that wants advertisers for people who want to buy more freight! Demand is a great reason why!)
In reality, I'm almost 100% sure that the real reason for the congestion is referred to in the one sentence from Hapag-Lloyd - which is that port workers in SoCal have been decimated by COVID. The massive spike of COVID cases in Los Angeles County that started ~11/1 and really hit hard by 12/1 (discussed many places), which has disproportionally impacted both POCs and workers in heavy-labor industries, is certainly impacting the supply of workers to offload and process. I've heard this anecdotally from two friends who run freight forwarding companies in SoCal.
It's also worth noting that the logic around shipping ahead to predict a generic increase in consumer spending doesn't play out. Planning for a single date (Halloween costumes, Christmas toys) - of course, ship it as close to the deadline as you can, but don't f'ing miss it. But for a rolling, undated, potential increase in spending? In a world of relatively fast manufacturing, ~4 weeks to get your items from the Shenzhen terminal to offloaded in Long Beach, and with storage costs being exponentially higher in the US than in China - it makes zero sense for what will be a diffuse wave (optimistically!) of consumer spending. No major manufacturer/retailer produces that far ahead of unproven demand, and no smaller one can afford to do it (and it's not like you can get money for this).
This is a staffing shortage, pure and simple. It's not going to get better for a while.

BTW, I didn't see this before I posted, but Ryan Petersen (CEO of Flexport) shared on Twitter today
"Yesterday there were 800 COVID-19 cases amongst the 9,000 ILWU employees who run the port of LA / Long Beach. And there was already a backlog of 29 container ships waiting to unload in the port."
