USA made. Just like Whirlpool, Maytag, Amana, Frigidaire, GE, Roper, Hotpoint, Admiral, Estate and I'm sure many others I'm forgetting. If that's you're only selling point you'd better keep trying.
As for price and performance, if you are talking top loaders (I assume you are based on the $600 price you quoted) the highest rated Speed Queen is rated only "fair" by Consumer Reports and costs more than FORTY EIGHT of the models rated ahead of it.
Maytag is no longer in Newton. Maytag closed down in Galesburg, plus Herrin, IL and in Arkansas. Maytag's are made in Mexico and all the Galesburg jobs, 1,500 or so, left Illinois for Mexico. Amana is no longer in Amana. Should I keep going?
Walk into any laundromat. What do you see? Speed Queen. They take the abuse.
May cost more because they are made in the USA.
From the website: Made in America and refined for more than a century, our innovative technology and proven performance deliver the reliable operation you’ve come to expect from the most profitable brand to own in commercial laundry.
Ask Whirlpool where they make all or nearly all of the models now since they bought Maytag, Amana and more. I couldn't find Made in America on the Whirlpool website.
Ask in Louisville where GE are now made? Overseas.
Go ahead buy Mexican or Chinese. I say buy USA.
