When idiomatic expressions come into being, they show how we as a culture feel. Take, for instance, the expression, “It’s just business”. Don’t take it personally. It’s not personal, I actually like you. Sorry, but this is business.
It means that business takes precedent and sets the tone for what becomes human behavior. We have to do what we do because it makes business sense.
And thus the question arises: What is “good” for business? Obviously, need, demand, and survival.
What is good for a business that manufactures weapons is not what is good for a business that needs peace, harmony, kindness, and family time.
Once “business” permits, justifies and promotes deceit, fear, and moral transgressions, well, then the idiomatic expressions arise, and, no holds barred.
