Has everything we buy reduced in quality over time? Has anything increased in quality or stayed high quality and durable?

I saw this interesting Tweet about the degradation of Barbie doll quality after recently watching this youtube video about the reduction in clothing quality to include more plastic and make everything stretchy so one size fits more variability. I have known for a long time about PYREX vs pyrex.

Phones used to be indestructible, but now they need upgrades every few years to maintain speed.

I noticed it most with clothes. My favourite brand of clothes at university was Jack Wills. Almost all my purchases were second hand. Then they got bought by Sports Direct and the quality dropped hugely.

Are there any categories where you can still buy high quality durable items across the board?
