As a photographer, I completely agree with you. The difference between a professional photographer and a large pizza today, is that a large pizza can still feed a family of four!
With the improvements in cameras in recent years, it has meant that just about anyone can pick up a camera and get a well exposed image that is in focus today. In the old days, you had to understand light and settings to get a correctly exposed image plus you had to properly focus the camera to get a sharp image. There was a lot to know about.
Today just because the camera does most of the work for a person, almost everyone thinks they are now professional photographers. And unfortunately, at least half the stupid public believe them. The other problem for today's real photographers, is educating the public as to what is and what is not a good photograph.
Yes, the great digital cameras of today can correctly focus and expose an image, but it cannot pose a group, compose a scene nor set up the lighting like a true professional photographer can do. I see these people all over the place on beaches and in parks, doing family photo sessions or senior shots or weddings, and for the most part, these people behind the cameras, are not photographer, they are Fauxtographers.
As a true professional you can see from their nonexistent posing abilities to their poor choice of light falling on their subjects to their choice of location and background in their scene, that these camera holders haven't got a clue as to what goes into creating a great photo. As long as they are low cost, the customers seem to be happy with the crap they are churning out.
If someone's mum was a crap cook but that is all they knew for food, they would think it's fine. Not until they get to taste a great dinner would they suddenly know the difference. And this is the problem in photography, only when they have had a really good family photo taken by a professional, for example, will they be able to recognize the difference between the mediocre, at best, crap they have been buying, compared to a beautiful family photo.
Unfortunately, very few other professions have been affected in this way, as has been photographers.
