In my experience a label changes the way we regard someone or something. We make jokes about our chores by calling ourselves “waste engineer” as we clean the toilet or “VP finance” as we pay the mortgage. Even though we are kidding around in the moment the serious edge behind it is that by using a more elevated title the job gains a higher level of respect. I believe that is true of the hard working farm laborers who make it possible for us to eat a huge variety of fresh and healthy food without doing the backbreaking work of growing and harvesting it ourselves. When we use a respectful name for anything, we humans almost always tend to show more respect for the names person, item, or idea.
