Mass production can create big benefits or great harm, just like people by themselves.
https://en.m.wikipedia.org/wiki/Toxic_oil_syndrome
300 people died, and a "few" thousands permanently disabled because of "contaminated" oil, which was totally not cheap industrial oil resold as food grade oil for profits.
This happened in Spain and recently you still have oil scandals in Europe, where the oil being sold is just oil that the human body barely tolerates.
