Much of Miele's North American pricing comes from fact everything is imported, as such subject to exchange rates and shipping costs.
Unlike Bosch, Miele refuses to build a plant in USA much less North America so there you are...
Parts, accessories and supplies found rather cheaply in EU, are all quite dear in North America, this included the vastly inflated rates once charged for Henkel products (Persil, Somat, etc...) and even Miele's own label products.
Then you simply have fact Miele is a small player in rather large North American market. They don't move anywhere near number of products as Whirlpool or Electrolux (either under their brand names or subsidiaries). Without that economy of scale what is sold cost more than it otherwise would.
Keep in mind while yes Miele laundry appliances are rather good, we in USA don't have access to a wide array of things from other brands that are equally or offer better value than Miele.
Miele's gamble with 4XXX series washers and matching dryers was their attempt at breaking into a larger share of North American laundry appliance market, something that is vastly different than their home manor (EU).
While it has taken time for Americans to warm to front loaders, one thing is clear; they didn't like "compact" units in large numbers. For all its faults Maytag's Neptune showed the way. Americans would use front loaders if doing so didn't dramatically alter time honored laundry habits. That is doing large amounts of laundry at a go; this rather than small amounts on near daily basis.
Most American uber sized front loaders have rated capacity of 18 lbs. This is highest most brands will go because often local zoning restricts residential washers to 20 lbs or less (New York City is one).
Miele's Little Giant washers only rate at 15 lbs, and are very expensive for what you get. That and have unique electrical power requirements often not found in American homes. So Miele tried another track, came up with 4XXX series, and we know how that ended.
Miele went back to drawing board and came up with W 1 series (rated capacity of 17.6 lbs). More importantly various EU markets now are more receptive to "large" capacity washers. So Miele isn't stuck with making machines just for North America (as with 4XXX series).
Where Miele fails, and Whirlpool, Electrolux etc... eat their lunch is that for money paid for their appliances Miele USA still has weak after sales/service
Someone who has paid nearly three thousand for a washing machine doesn't want to hear they will have to wait two weeks (or more) just for a diagnose call out. Then maybe another week (or more, much more) before repair can be done. Worse that is if things can be fixed at all second call around.
