Be aware that survivorship bias may fool you when comparing the quality of new and old items. The single juicer that lasts 70 years may be the only one of its kind to last that long, the others from the same production year being left to rot and rust in a landfill.

That being said, I definitely believe that planned obsolesence and unintentional bad quality is a plague on modern consumer items. I am lucky enough to have the time, knowledge, persistence and money to research and buy long lasting goods. For example, I have bought kitchen knives made out of a single piece of metal, which are therefore less prone to breaking than the run-off-the-mill ones. My jeans are from a Swedish jeans company that offer in-store repairs as long as it's practical. This is saving me money and effort in the long run. However, I do not believe in such individual solutions to what is essentially a systemic problem; people should expect good consumer items without researching beforehand like it was their hobby.

I'm glad that the EU is working hard on right-to-repair laws.
