Query: Planned Obsolescence

Planned obsolescence or built-in obsolescence in industrial design is a policy of planning or designing a product with a limited useful life, so it will become obsolete, that is, no longer functional after a certain period of time.I have owned this grinder for about a year and a half, and this morning, the PLASTIC parts of it began to disintegrate and have rendered the grinder completely worthless. Before completely falling apart, though, the plastic managed to be partially ground into my coffee, so I had to throw that out too.I won't be buying another Cuisinart grinder. Whatever happened to producing items with quality and durability? Now I have a contribution for the landfill.
