Korky actually does make a pretty nice plunger in Wisconsin.
For the gentleman, I think there are two issues. The first is, "Where is it made?", which is the one I thought he was concerned about. The reasoning that most people have behind that one is that they want to help keep jobs here by buying things that are made here. Toto's products generally meet that requirement; they are doing more than CraneEljerStandard to actually employ Americans to make product here, and I think they deserve our support.
The "foreign company" issue is a little difficult. If I start a toilet company in the United States, employ say 5,000 people in administrative positions in Georgia and around the country, and those administrators build a manufacturing infrastructure that employs Americans, does anybody care what country I am a citizen of? If so, does it matter if I am a citizen of one of our strongest allies in the world? If Joe Smith from Utah founded the company and grew it, and then sold it to someone from someplace else who left everything intact, do we care who owns it? It's an issue that quickly becomes a conundrum.
That said, I love the Korky folks, who do everything in Wisconsin, and do a lot right, particularly as regards customer satisfaction. They are super eager to please; they have even started participating in the comments sections of reviews on retailer web sites to answer questions, solve problems, suggest refunds, etc. If they made a toilet, I would give it serious consideration. But they don't. Of course, the next best thing is to buy the toilet that uses their parts. Just sayin'.
Interestingly, of course, Mansfield is owned by Corona, a Columbian company. Just like TotoUSA is owned by Toto, a Japanese company.
Mansfield stamps "many" of its toilets 'Made in USA", but not all. They are talking about the China.
Mansfield uses the Fluidmaster 400A as the fill valve on many of its toilets. The 400A is MADE IN MEXICO. And, of course, the heinous WDI Eco-Flush is Made in China.
So...if the gentleman wants to stay true to his beliefs, he probably is pretty much in the same place buying Toto as Mansfield.
Toto: Much china made in USA, mostly USA guts, USA manufacturer owned by Japanese.
Mansfield: Much china made in USA, much Mexican guts, USA manufacturer owned by Columbians.
