"Writing is manual labor of the mind: a job, like laying pipe." — John Gregory Dunne

"Until very recently, when an author's work was copied for educational use, it was usual for that author to receive some compensation through licensing agreements.

     New guidelines published by a number of Canadian educational institutions and organizations claim substantially large portions of printed works are now 'short excerpts' covered by fair dealing.
     The result of such a change in copying practice would be the loss of millions of dollars in annual license revenues for Canadian authors. That is real earned income for real taxpaying Canadians who play a vitally important partnership role in education.

What if other professionals were required to provide schools with their services and expertise free of charge?
     Here's the above passage (my apologies to the author) with a slight change of focus, so to speak... 

"Until very recently, when a plumber was needed in an educational facility, it was usual for that plumber to receive compensation, usually through an ongoing service call agreement.
     New guidelines published by a number of Canadian educational institutions and organizations claim that a large portion of plumbing problems such as plugged toilets are minor and should be rectified at no cost to the education facility.
     The result of such a change in practice would be the loss of millions of dollars in annual revenues for Canadian plumbers. That is real earned income for real taxpaying Canadians who play a vitally important role in education.
     Does the expectation that the washroom toilets of an educational institution be maintained without payment seem fair to you?"
