I have no idea where you got that.
I am for charging those who receive the direct benefit with the cost of foreign imports. I do not favor subsidizing imports.
I am wondering why you choose to increase tariffs rather than docking fees. If you increase tariffs, then shippers who use the ports around LA will pay more money for the costs you say they are creating; but so will shippers who use the ports of Washington and Oregon and Louisiana and Texas, where they may not have those costs to the same degree you see in California!
Essentially, you are forcing ALL ports to increase the charge on incoming product, regardless of the need of those ports to raise additional capital.
So, if your issue really is the infrastructure costs created by shipping, then wouldn't it be logical to simply increase the fees at a given port to cover the costs of that port? Rather than force ALL ports and states to increase their costs, regardless of the need to do so?
