I think it’s mostly a supply-line issue now. The container ship Ever-something obstructing the Suez Canal for a week, and now the largest port with respect to container shipping in China being closed because of the pandemic, are amplifying the issues that the governments have caused via the shutdowns. The labor shortage resulted in fewer dock workers in the ports in California, and container ships were lined up waiting to be unloaded and then reloaded with stuff to go back across the Pacific. Some writers connect the labor shortage with the augmented unemployment insurance monies.
There hasn't been a container ship trapped in the Suez Canal for the past year and a half.
