If people didn't wag the fare, do you think the rest of you would benefit from a reduction in fares?
Ultimately yes.
The biggest problem I have with people that do dishonest things is that they are, humm how do I put this carefully, dishonest.
But no doubt you will now assure me that you would not display this trait when it comes to pushing the envelope in flying. So that I can safely fly the aeroplane after you have just nibbled the G limits or landed that bit harder.
