Fair question, I personally believe that capitalism runs on money, so stopping things like the rapid decline of manufacturing quality can only be achieved by not playing their game and not giving them money. In this case you could either do it by making things yourself, or by buying things second hand so that the original manufacturer doesn’t profit from it. The second option is definitely more practical, but making things from scratch is also pretty fun

There is of course a heavy dose of privilege involved, as there definitely are paradoxical situations where you can’t afford to not support shitty practices. Doesn’t mean that it’s all pointless for all of us and no one should ever try.
