All sorts of things (both supply and demand side) are misaligned with respect to minimizing wastage as a whole.
And that all being said, there really is something valuable about the 'cheap product' thinking - and that's specifically the mindset of decoupling your enjoyment and utility of a product from its up-front cost. And this is valuable, because the very thing that we need to do to minimize waste is to increase the up-front cost of like... everything.
