I’ll be blunt, a lot of this is just how the system works. If products lasted forever companies wouldn’t sell nearly as many. Businesses aren’t charities, they’re trying to stay profitable. It might feel annoying as a consumer but economically it kind of makes sense.
But there’s still a responsibility involved. Profit doesn’t mean companies should deliberately make worse products. The environmental impact alone should make companies rethink designing things that are basically disposable after a few years.
