capitalism is not efficient. it's not only that it's exploitative, extractive, and destructive even to itself, but that even by its own metrics, it's a failure. massive duplication of effort forced by 'competition', entire fields of industry that are basically just pyramid schemes (see: tech, finance), waste on an enormous scale (retailers destroying their own product to maintain scarcity), pretend meritocracy pushing the most bumbling failsons on the planet perpetually upward...
@Paradox @esvrld Regarding (b), it's overly simplistic to say whether capitalism is efficient or not. In some contexts it's effecient (e.g. a company reducing waste) & in other contexts it's absurdly inefficient (e.g. different companies writing the same closed-source proprietary s/w code). OTOH, the widespread misconception is that it's wholly efficient and that badly needs exposure.
