uhm, meaning is instilled, we do these things based on incentive, a currency which provides a mutual utility. the actual value of which is dependant on a number of factors, but your statement is only true if you regard a specific scope, and confirm that there is no utility being derived. essential Industry which provides resources for transportation, infrastructure for agriculture and derived processes are all tangibly benificial to society as a whole. You go to school to feed your mind, just as you go to your fridge to feed your face. Now, if we're talking existential inherent value, I still disagree with you, because you are saying inherant utility is without value, which is ignorant and misguided, I think. If you disagree with the system, that's a completely different "universal truth," I'm sure what you're referring to are non-essential industries like speculative markets, luxury products and products created through synthetic and social demand (makeup, window stickers of family members on cars etc.). I just take issue with such a broad and non-specific statement that does not inclusively nor exclusively pertain to industry as a whole.
