"What I do know is the health professionals are far better organised than most, and sadly that includes mine. In particular they seem to be very good at limiting the number of people who are allowed to enter their ranks."

Ironically economists would preach the supply and demand axiom yet they don't limit their own intake as far as I am aware. Limiting the number of people allowed to enter guarantees a strong demand and maintains a lucrative supply for the scarce professional resources. They certainly are well organised.
