Webadict’s statement:

you have to admit that the bottom line is the chief concern here, and not the safety of the workers of consumers.

Clinicallydepressedpoochie’s response:

We are far beyond seamstresses burning up in a building with no escape route. The cost of an incident has tangible costs. How will production continue if your sugar mills keep blowing up? Who will make your product if your workers keep breaking their backs? How will tribal knowledge of your process be preserved if your workers keep dying from inhaling toxic fumes? How will you meet deadlines if you’re equipment keeps igniting?

As an aside: what profit do workers make when they’re employees? They didn’t invest in the business. They are selling their time/energy (or labour) to the company at a certain rate. You’d have to compare that rate to the value of any other potential salary, as well as minus health and stress costs, plus take into account the value of non-economic activity that could also use those resources.
