I'm looking for a simple explanation of what is causing this backlog of container ships off the California coast. I've been seeing a wide ranges of reasons including: A) environmental California trucking regulations from the California Air Resources Board which mandates all trucks must be 2011 or newer. B) CA law AB-5 which bans bans owner operators which was aimed at Uber and Lyft drivers but encompassed and banned almost all freelance jobs. C) Biden/Newsom vaccine mandates. Is it a combination of all of this and or some other factors? Democrats talk about a lack of truck drivers but why...
