I think that shows the difference between a true hunter and a tourist with a gun. A true Hunter will put all reasonable effort into retrieving wounded game, it's a responsibility.
Don't get me wrong, many what I call Sunday Hunters are pretty darned good.
I actually enjoy tracking, not everybody does. I really enjoy working my Dog. My eyes are getting bad, I'm not nearly as good at it as I once was, I use my Dog more.
I think many are just lazy and put off something they don't enjoy as long as possible.
