If the public option turns into a take-over, then it's going to put a strain on the quality and number of doctors out there. I have a few friends who are med students and I know someone who is an advisor for pre-meds and they all agree: most, not all, enter med school for the high-earning salaries. Yes, a small number are in it for altruistic reasons, but let's be real here. Anyways, that's another issue. So, if it's a single-payer system, salaries will be lowered, by how much I don't know, but you can't deny that this will impact physician salaries. This will mean in less interest in people to become doctors. If less people are interested, then there will be a shortage of practicing physicians. So, by supply and demand, to meet an increase in health care consumers (via expansion of coverage) there has to obviously be an increase in physicians. How to do that? Ease up medical school admissions significantly. Med school admissions rate are notoriously low (2%-24% of applicants get in, depending on the school); average GPAs are about 3.7. So if admission standards are lowered, the high standards of doctors will go down. On the other hand, a tougher admissions process results in a lot of hard work in students--ever meet a pre-med or med student? They are always studying their butts off because it is extremely competitive. Imagine being a student, and you know it's easy, wouldn't you just study up to the minimum to get by? Also, Med school is extremely expensive and many end up $200K -$300K in debt. Would people want to be in that kind of debt and make a slightly above average salary?
