http://thenextweb.com/dd/2015/07/28/why-everyone-is-a-designer-but-shouldnt-design/Why everyone is a photographer and some people shouldn't be. Look at the photo credits, Shutterstock and creative commons. Do creative commons get paid for the use. The story hits a point why some people shouldn't be in Micro. I see the same arguments about professional as here.
I'll fall on the sword to start this. Everybody who is a stock photographer making money is a designer. It's part of the same work to take a good stock photo. I design it and shoot it. I make money, I'm a professional.
