I'm glad you pointed out those free online educational resources, because I think they're revolutionary. The Khan Academy is awesome. Salman Khan gave
this great TED talk a while back describing how it all started. What an inspiring story!
Unfortunately, I fear that technology evolves much more rapidly than traditions and cultural norms do. We do not yet live in a world where a self-taught person--no matter how demonstrably proficient--is in the same ballpark of opportunity as a person with a formal degree from an accredited institution. Most people would not agree to let a self-taught person give them medical treatment, most companies will tend to hire someone with a formal degree over a self-taught person, and so on. I sincerely hope that changes--and soon--but for the moment we seem to be stuck in a system that effectively requires us to pay an obscene amount of money to receive the educational imprimatur of the State. Unless, that is, one prefers to pick lettuce, wash dishes, or
bounce bars while developing new cosmological theories.

With health care, you've got that mixed bag of much better care and technology but with much higher prices. On the one hand, my parents talk very fondly of a time when doctors made house calls and you simply paid them directly (at an affordable price) right out of your pocket. Insurance was insurance, not a prepaid health plan, and government interference in that market was minimal. On the other hand, I'm extremely happy that modern miracles like the MRI machine are so accessible.
Funny you should mention that. My father, a retired physician, has often lamented that many of the modern high-tech medical tests--while amazing and invaluable when used in the appropriate situations--are grossly overused due to "defensive medicine." That term refers to the ultra-conservative way in which many doctors now practice medicine as a result of the growth in (successful) medical malpractice lawsuits in recent decades. Enough doctors got their asses handed to them in court that they gradually started to order all sorts of tests and procedures for their patients that their training clearly taught them were unnecessary.
Based on simple physical symptoms alone, doctors can generally diagnose something straightforward like a broken bone or a sprain with a
very high likelihood of being correct. But because the tiny number of diagnoses that turn out to be incorrect have the potential to financially ruin the doctor (think
Black Swan effects), he is all but forced to order all sorts of extra tests to prove his diagnosis beyond the shadow of a doubt. It sounds very nice and thorough, but in many doctors' estimation, it is wasteful and increases the cost of medical care significantly for everyone.
I guess what I'm trying to say is that the existence of new high-tech medical procedures like MRIs are indeed a good thing, but they are by no means as necessary for the average person as we tend to think. A lot of medical care is for standard checkups and emergency room stuff like broken bones, bad cuts requiring stitches, really bad fevers, etc. Checkups and treatments for those kinds of basic medical issues generally do not need to be super-high-tech, yet they're growing in cost just like the more technology-intensive treatments (e.g., surgeries, cancer treatments, brain scans, etc.). That is the sense in which I see the growing cost of medical care in recent years as being a net burden on most people rather than a reflection of universally better medical care.
