It'll also serve to weed out the intelligence. Look at the state of public education in the US. Teachers are practically expected to provide charity work; entry-level teachers are paid crap, work long hours, and have next to zero job security. It's no wonder that the smart kids are running away from teaching and into stable and/or high-income fields... like medicine. Let's see... rewarding career + money or rewarding career + no money... hmm...
Funny, I manage to pay my mortgage, save for college, pay down my student debt, pay daycare for 2 kids, buy reasonable cars, go on vacations, and improve my home on my $(less-than-75k) salary. The problem that's run into by so many here is the expectation that "Because I sacrificed 7 extra years of my life and $xxx,xxx extra in student loans, I should get to live in a $500,000 house and drive a $50,000 car and go to Fiji for holiday and my wife will never work." Um, no. It'd be nice, but that's not the real world. You have to be realistic about what a physician salary buys you, and I'm willing to bet that in most cases it's not those things, at least not to start.
Physicians should be paid for their skills, training, and expertise, yes. I don't think $75k/yr is a fair compensation. And I totally agree that the current system is a mockery of the free market; insurance and the government tell you what they'll pay you, and if you don't like it, tough titties. There's a lot that can be done to improve on that front. However, the general assertion on this board about $75k not being enough to live on smacks of ignorance or irresponsibility or entitlement and frankly just pisses me off.
