It's less clear cut than that, because modern materials can be better at the job they are designed for. An IKEA kitchen, for instance, might not use traditional wood or stone for its benchtops, but the materials used are actually better in terms of cleaning and handling food on them. It's just that these improvements often get bundled with cheap plastic and parts in other parts of the kitchen to keep costs down.

Similarly, cars today are far superior to old cars in terms of safety, and the gains that have been made on the engine side of things are nothing short of incredible. Every modern car is essentially a supercar by the standards of the 90s in terms of oomph per unit of displacement. The problem is that all of the systems have been coupled together, often needlessly, in order to improve telemetry and capture a bigger share of the used market. It's hostile towards the end user.

There's no question that the level of quality today is higher, especially where it matters. It's just that value extraction eventually turns hostile towards consumers in the absence of real competition and the need for endless growth.
