Right, I'm going to say this straight up - you, dear poster, are grossly misinformed, and decidedly disconnected in reason.
1) The number of doctors in Adelaide has absolutely NOTHING to do with the competition for places in Medicine at UNSW.
The number of doctors is more important when considering how many are needed, versus how many we can train. This in turn affects the number of medical places we need, and since we obviously need more the government has created more places. Sadly, they have failed to equally expand the resources necessary to TRAIN said doctors, meaning that medical schools are forced to maintain the restricted intake until they can actually AFFORD the (very expensive) facilities and staff necessary to pump these doctors through.
2) Competition will never be uniform anywhere, in anything, ever.
Tell me, are house prices in Liverpool as high as in Vaucluse? Or are there as many flights between Sydney and Melbourne as between Brisbane and Adelaide? Location means a lot, and some locations are far more lucrative than others. Though the competition for places in medical school is more or less uniform (a little higher in the Sydney and Melbourne schools), competition for graduate work is VERY different. It is a reality that young, reasonably-paid professionals who have spent their entire self-aware life studying are most interested in living where there is a lifestyle suited to their tastes. For most young doctors, this means Sydney (and for the rejects, Melbourne). This most certainly does NOT mean Adelaide, Perth, Hobart, Brisbane or (Lord help us) Darwin.
Furthermore, there is a UNIVERSAL shortage of medical professionals - the greater competition for major cities only means they can be a little more picky, not that they are flooded with applicants. Any city outside the inner west is short-staffed, and depends on Sydney's popularity with interstate graduates to fill shoes. What happens in those cities without such a convenient card to play? Even more importantly, patient "queues" are so long because patients are presenting when they really shouldn't - like coming to the emergency room with your choking baby, and then signing in the other three kids "for a check-up". Or running three kilometres and complaining of leg pain.
3) We are professionals, NOT salesmen
Health is not something you simply buy - it is something you either earn or luck into. Doctors are not there to please your every whim, we are busy, highly trained individuals with a job to do. Don't just come in to our office with a checklist of demands - you will NEVER be satisfied, and we don't care. Be realistic - we will do what we can for you, and if you cooperate things will usually, hopefully, go well.
4) We are not your servants
Very much related to the above point. Who are you to tell doctors what kinds of hours they should work, or what kind of standards they should perform to? You are not a CUSTOMER, you are a PATIENT. If we wanted to simply serve we'd have gone to maid school or whatever - doctors are human too, and have to deal with a whole lot more shit than "normal people". Doctors need sleep, they need leisure, they need love and they need YOU to get the fuck out and stop telling them how to do their job. Maybe if you came and tried it out you could give some "feedback" but until then, no way. How many dying people do non-doctors have to handle in a given day? Distraught families? Crippled athletes? Elderly widows, suddenly left entirely alone? This is way more emotional damage than can be handled just walking off the street - telling someone they're not good enough because they can't go without sleep and food is quite simply an insult to one's own intelligence.
Plus, it's damn well unsafe - if you get tired after working in Coles for eight hours, you might give someone the wrong change. If we get tired after working eight hours of surgery, we might give someone the wrong lungs. Big difference. Of course, the wrong drugs are more likely, and definitely more lethal.
5) Doctors have just as much right to leave their job as everyone else
Have you ever considered why a young doctor may choose to quit? Perhaps the hours are affecting his family life, or the environment is hostile, or maybe he plain doesn't like the area he's currently handling (emergency, for example). These things are common to all professions, and any sane person can agree that such problems would interfere with a person mentally, emotionally, and physically. However, in medicine such deterioration leads to personal dangers for patients - an exhausted, unhappy doctor with problems with his family is NOT going to be as effective a clinician as one without these problems. In fact, doctors are ethically bound to leave their posts if they realise the safety of their patients is compromised - it's better to have one less doctor than a dangerous one.
6) In short, L2P nubcake
We are human beings who have to perform a superhuman function. Until you understand just what is going on, you do NOT have the right to make judgement. I invite you to read beyond the simpleton message of Today Tonight, and actually see what doctors and other health professionals deal with. Then, when you are truly informed, contemplate the grievances you have aired above.
If anything I have posted offends you, then keep in mind it is because everything you posted offended me - and all other members of the medical sphere.
