Where do you think the money is going to come from? If it's from the pockets of these many physicians, I doubt they will be eager to help. And besides, physicians who already did their duty as a resident aren't going to care that you are suffering what they already suffered. In fact with changes to hours and the annual cost of living increases that have occurred, most post-resident physicians are going to look at your plight and thing, "boy these guys have it a lot better than I had it".
Not to mention that most residents won't line up with you to argue about salary. Most don't even look at it as a real salary, it's just something you get paid while you serve your time until you get your salary. It's thus looked at more of a stipend, since you are in training. Is it very low income for someone with a lot of schooling? sure. Is it unreasonable based on your actual profitability? Probably not. You are a big cost. They have to pay lots of medmal insurance, and incur lots of administrative and training costs, and you end up slowing things down to some extent, at least during the early years, because you are still learning. The government subsidizes you nicely and makes it very worth it to hospitals, but without that, few places are ponying up their own money to fund unfunded spots, which suggests to me that residents are not as big money makers as some suggest (although I suspect that with the government funding and what a resident generates, the profits outweigh the costs pretty nicely).
