The only difference is the scale though, right? Now where do you draw the line, somewhere above 7.5k AA but below thousands of dollars? The 2nd prong is a non-issue if there's nothing unethical going on.
Not knowing where to draw the line does not mean there is no line. Most people can tell when someone has gone over the line, without being able to pinpoint where the line is.
Example: Talking is normal, right? Let's say 1 person talks to a store employee and another yells at an employee, is the person yelling acting ethically?
Now where do you draw the line between talking and yelling?
Which exact decibel does a person switch over from talking to yelling?
Does the fact that you and I don't know the exact decibel, change your perception of the person yelling?
