Good Article, it touches many other issues in Higher Ed (perhaps for another post).
I have mixed feelings. It is understandable but misguided.
They want young dentists to be able to get jobs. I think everyone does. The problem is they want to achieve it by running a legislative protection racket. They want to guarantee dentists get jobs by using the laws of this country to put a hard limit on how many people can become dentists in the first place.
It's clever, it’s supply side. They are reducing intake, they are not denying those who are already dentists but denying people the chance to even become one and aim for a job. Imagine if we attempted to choke the number of workers in any other industry - Bakers, Construction Workers, Accountants or Musicians. It seems bizarre. It boils down to the dentists wanting special treatment, should we give it to them?
460 is a suspiciously round number. They put in all kinds of statistics and came out with exactly that?
One of the reasons centrally planned economies (e.g. Soviet Union) fail is because there is a problem with a central body planning certain things out. Often, they do a worse job than if you left the market alone. In setting the supposedly scientifically rigorous digit of 460, how can we be sure we aren't sowing the seeds of a future shortage or glut?
I think it's nearing a kind of entitlement. We're uni graduates, we're dentists, we shouldn't have unemployment like other professions! In the 1960s, only 3% of people were university graduates. It might of made sense then but the time of a closed shop of privilege and entitlement has now long passed.
( Not to say that i dont think there are problems. Not an expert on this issue, i dont know everything about it, open to having my mind changed. There are many things i left out, my posts can get long. There is more justification and meat to it than this but probably better suited to a thread on univeristy/jobs/caps in general)
