I'm no expert in this issue and don't quite know all of the details, but as I read the discussion, I get certain impressions. Some thoughts:
-Physicians are a necessary facet of society. This isn't really something that we can just let the free market regulate, because a lot of people will suffer in the process. Think about it: let's say medical school tuition increases to 60-80K/year on average, not including living expenses. Meanwhile, physician salaries continue to decrease for practicing physicians, and student loan interest continues its upward climb. It'll reach a breaking point when becoming a physician is a net loss, so fewer people will do it. This is free market economics - the return doesn't match the investment, so demand goes down. But this isn't just some product - this will lead to a massive physician shortage, which in turn will affect the general health of the public in the United States. So, while the free market is "correcting" itself (schools start lowering tuition to try to increase attendance), in theory, a large number of people will suffer and die from illnesses which likely could have been prevented or cured simply because there weren't enough physicians to treat them all. This isn't even considering medicare/insurance implications to pay those few physicians to take on so many patients anyway, and since we're trying to head toward universal coverage in some form, it can be assumed that the cost and strain for the budget will be large as well. In short, just letting the free market control this issue will cross into ethical and human rights issues not seen in other sectors since the services provided by physicians are often an absolute necessity.
-We do need to be careful of government meddling into private matters like private school tuition, since this often is a segway into more tight and unproductive regulation. I don't have a specific solution in mind when it comes to this problem of balancing between public interests and private freedom, but I do think that one area to consider changing is that of public support for private programs which are raising tuition, rather than imposing strict and binding limits on tuition itself. We need to think of incentivizing/disincentivizing rather than coercion, which is a common temptation when dealing with those whose actions we consider harmful.
-What is the purpose of student loan forgiveness for public servants? If I'm seeing this from the right angle, it seems to be there as an extra incentive to make up for the pay cut taken by public sector employees when compared to their private sector counterparts. Whether or not to axe these programs will be a good or bad idea depending on the profile and circumstances of those to whom it applies. A better choice might be to decrease the degree of forgiveness rather than to cut it completely, such that the ratio of debt to salary for public employees should be roughly equal or somewhat less than what is typically seen in the private sector. Provided tuition rates don't rise out of control, as discussed above, which would make any public sector work much more of a burden.
-NN makes an interesting point about the culture of the US changing with respect to success, and this is an important overarching theme when it comes to dealing with these issues, since social climate is a big factor in how much of the populace is going to behave. General ambition in the workplace seems to be on the decline, which of course will factor in when considering that, from a healthcare standpoint, the costs of entering the profession are only increasing at the moment.
