I thoroughly enjoyed "Debt"'s perspective on social-economic collaboration, money, credit, debt, and contract arbitration. It's a very informative and thought provoking book.
"Bullshit" grossly misses some fundamental aspects about modern markets and power structures and as a result turns into an insipid, meandering grievance without substance. The commentary mistakes social-welfare states which have monopoly enforcement on: credit repayment (legal tender), and authoritarian control of the means of production (permitting) as capitalism (_private_ ownership and deployment of goods and services). As a result, the entire subsequent criticism that follows in the book is misguided. If I had to summarize it: "Economic (consumer's-goods) producers are supremely inefficient in the deployment of labor, resources, time, production quantity which results in a social malaise". It implicitly pathologizes the choices of people who work in the "bullshit" jobs as unable to make nuanced, multivariable decisions. Yes, it may be the case a security camera would be a more efficient observer to an empty lot than paying a human, bored out of their mind, to sit in a hut. But that critique denies the economic calculus the hut worker made, that this job was the most ideal option out of the many different dimensions available to them.
If the set of available options cannot be combined to produce desired results, it's not possible to combine inputs among a further reduced set of options to produce the desired results ("regulation"). The only option is to increase the set of available options (liberalization, de-monopolization), to produce different outcomes. The entire book fails to address to roll of entrepreneurship, e.g. a speculative endeavor by an individual or group that they can deploy labor, resources, time, production quantity in a more ideal and enjoyable arrangement. The absence is a shame because instead of the book being a diatribe, it could have been a powerful call to action to improve our lot.
