2. Much of the stuff that comes through western ports are coming to the east coast. Things being shipped from China/Japan/etc are usually brought across the US as far as I'm aware.

> It's much more efficient than trucking across the whole country.
I don't think this checks out on a time perspective. 15 days to get to CA = 15 days for the trucking route, or air. I think both get there under 15 days. Fuel efficiency, maybe, I'd need to do more research. And it seems like the bigger factor is not final destination but the other stops of the shipper, e.g going and dropping in Europe for the Suez.
See section 3.1 here for timing being quicker to truck: https://guidedimports.com/shipping-from-china-to-us/
Actually glad I went on this journey for some learnings along the way, but I guess the point here is that west coast consumption levels have nothing to do with this supply chain issue. I live near you too FWIW, not in this for defending my own west coast dog in this fight, but more to try and see why you were so quick to jump on west coast consumption!
Either way, you're not responding to the original point: east vs west consumption has nothing to do with the trend
But there are a number of container ships that are bigger than Panamax (the largest size that can fit through the Panama Canal). They can't make it to the East Coast from Asia without going around South America, or else going through Suez.
And: "More efficient than trucking"? You could send them across the country on a train, instead of on a truck...
So the backups with LA and other ports are because of increased demand on the east coast, west coast, and everywhere in between.
