It's more a concerted effort to make repair expensive, unexpected, unfashionable and gratuitously difficult across as many industries as possible.
30 or 40 years ago nearly all simple products were repairable, easily and cheaply. You went to any major retailer and they'd have a spares section along with aisles of new product. All of them. You could buy a new element for your toaster, kettle, heater or coffee machine. They'd keep seals and limescale filters and so on. Some of these were standard enough that they'd fit a wide range of manufacturer's products. They'd still be there years after the particular model was discontinued. There'd be a few third party offerings that were rarely as long lasting but perhaps £1 or £2 instead of £3 or £4.
Now? Nowhere sells spares, nor are they an expected part of most products. A kettle manufacturer might condescend to carry a few consumables like a limescale filter for a year or two. Then charge you around £10 with £2 p&p for a simple piece of plastic. Want a replacement element? That's basically never a spare part any more, though they don't last any longer. A fridge manufacturer might charge £18 with £4.95 p&p for a thermistor and a little heat shrink tube, but no longer have the one of the three that fails most often available at all. For a few year old refrigerator. (recent actual examples)
For larger products manufacturers are combining parts and modules into indivisible units that might ease manufacture a microscopic amount, but absolutely make many simple repairs no longer possible. So what was recently a £20 simple repair to your fridge or cooker is now a £200 major component and more labour than it's probably worth.

I've spent years, decades, trying to. There are effectively none left. Even the most expensive brands are aiming to have you throw it away and buy another as soon as they can get away with. Which leaves who?
