> Price is 3-4 times higher but it lasts 5-10 times longer The problem is that if an Ikea furniture lasts 15 years then that's enough. People no longer need 50-100 years furniture, because nobody wants to inherit old stuff anymore. Life's circumstances change faster and buying quality often isn't worth it. Maybe a Miele dishwasher last twice as long at double the price. But it will become old after 10 years even so.
> People no longer need 50-100 years furniture, because nobody wants to inherit old stuff anymore. I'm going to challenge this assertion: did anyone, ever? Looking around in my parents' house (retirement age), there's no furniture from their parents (post-WW2). I don't remember whether my grandparents had any furniture of their parents in use either. I do recall going to the charity shops and finding older wooden fur…
So yes, people do want to inherit the old stuff. I have some IKEA stuff (the beds were just too big, and mattress sizes are different), it just can't compare.
