Like I said, your math doesn’t work.
There is a significant incremental cost for infrastructure to accomodate international imports, infrastructure that is not required for distribution of US products. Many of these costs are born by US and California taxpayers, and not passed on in the cost of the imported products. It acts as a double-whammy to US competitors who receive no such subsidy and pay more than their proportionate share.
The cost of illegal immigration is a whole nuther subject — please try to stay on topic.
You have stated there are costs, yet you do not show them. I have stated where you can find payments for those “costs” you claim.
So what are the costs? Where are they listed? And how are domestic suppliers hampered by not paying those costs?
The statement about illegal immigration was simply to point out that Government malfeasance with funds is universal; if a port authority cannot manage their charges and or set their fees appropriately then your anger should be directed at the port authority not the shippers.
