But at least you could buy devices that would last for decades and decades.

Try finding a washing machine these days, that will last for more than 5 years or so before something breaks and renders the machine useless.

You may be able to find an industrial machine, made for hotels or laundries. But it will be very expensive and likely be huge and it will need 3-phase power. It will also likely not have a spin cycle, so you'll have to either air dry your clothes for ages or buy a separate clothes spinner (most driers need the clothes to have been spin dried first).

Whether I buy a cheap Whirlpool or an expensive Miele/AEG/Bosch or whatever, the quality and longevity is universally shit.
