Seattle is a very minor league port. It's way, way behind LA area ports and even the Port of Tacoma does about 50% more annual volume than Seattle.
I just don't understand why we suddenly need to fill Walmart's shelves with bullshit that no one really needs, or that some American company can create. This was EXACTLY the DU line in their "Buy American, Buy Union" phase from like 2005-2007 or so (if I recall correctly). They decried the waste of giant ships belching exhaust and filling the Pacific with the human waste of Chinese shipworkers just to bring consumer goods to the US.
Now, suddenly, the fate of the US is vitally linked to that crap never, ever ending.
