Humans need a minimum of about 1,200 calories a day. If a human prices their services too low, they won't be able to afford to eat and will die. If a human prices their services too high, they won't be able to afford to eat and will die.
You cannot price your services however you want.
I know you think you said something interesting, but you really didn't. You can absolutely price your services however you want, and if you die pricing your services too high or low: well that was a silly thing to want.
That has nothing to do with what we are talking about though, and was not the point in the first place. An airline obviously cannot price their services too high or low and expect to survive. You didn't show how the user's comment made sense in the context that it was originally made, nor did you give a proper retort to my comment.
You just picked the wrong thing to focus on and contributed nothing to the conversation.
