If you kill or sicken people because you do not care about food safety, there is not much point in pursuing profit. You won't have any long term.
While I agree with your general point, I don't see a wanton disregard for food safety in the pursuit of profit by large or small business, and I have worked for both.
At a previous employer (family owned, 100 years plus in business), we were setting up systems for BRC certification. The constant drumbeat of "why do we have to spend money on this" was loud and clear.
A couple of presentations of "what happened to Company X" when they disregarded food safety was enough to change that mind set quickly. Are there bad people? Yes. Are there bad companies? Yes. Are there bad people and companies that don't care about food safety in the quest for the almighty dollar? There might be.
Said company was not "bad" per se, the culture just needed to be changed. It's not like they ignored food safety, I got everything I needed. They just did not understand "why" the requirements were necessary. Not their fault, actually. They are not food safety and quality professionals. That's why they hire people like you and me.
