a somewhat serious answer...
i don’t think those discussions are about other people spending their money
this is an enthusiast board, covering music and all things/equipment used to reproduce the music
as a shared passion, we who come here like to discuss and share our experiences and thoughts -- on what is good and bad, what is worthwhile and not worthwhile, what delivers value for the cost, and what doesn’t... so its not about other people spending money per se, that aspect is tangential... it is about an area of shared enthusiasm that we care about, want to be knowledgeable in, and in that world, in that pursuit, what is worth spending our money on to enhance our enjoyment
