@rbreich Imagine an industry that would go bankrupt if it was forced to pay to protect its workers from excessive heat. That sounds like an unworkable industry that should not have existed into the first place. It was profitable by exploiting the heat tolerance of actual human beings. Much like coal mines exploited the pulmonary health of its workers. It’s dumb for them to protest regulation, because their competition would be bound as well. Some increase in costs, passed on.
