Two pieces worth reading on health care innovation. First, Glenn Reynolds on his family:

President Obama talks about the importance of prevention in a way that suggests that when people have heart attacks it's their own fault. But my wife, a longtime vegetarian and marathon runner, had a freak heart attack at the age of 37.

It wasn't from too many Big Macs. After some rough patches, she's now doing well, thanks to an obscure and expensive anti-arrhythmic drug called Tikosyn, and an implantable cardioverter/defibrillator. Not too long ago, she'd have been largely bedridden. These medical innovations made the difference between the life of a near-invalid and a life that's close to normal.

My mother had a hip replacement. Her hip didn't break - she basically wore it out with exercise. When the pain got too bad, she got it replaced, and now she's moving around like before, only painlessly. Not too long ago, she would have been chairbound.

My father had prostate cancer; his doctor suggested waiting but on biopsy it turned out to be pretty aggressive. It was treated with radioactive "seed" implants. He's now been cancer-free for several years, without the side effects of earlier treatments -- or, worse, of cancer.

My daughter had endoscopic sinus surgery this spring. She had been sickly and listless, complaining of constant migraine headaches, missing a lot of school, and generally looking more like a zombie than a teenager. Several doctors dismissed her problems, or prescribed antibiotics that didn't help much, until we found one who took the extra step.

A head CT scan done on a fancy new in-office machine showed a nasty festering infection, the surgeon cleaned it out, and now she's like a normal kid again. Before laparoscopy, her condition

would probably have remained untreated, and she would have been another "sickly" kid. Better to be well.

The normal critique of socialized medicine is to point out that people have to wait a long time for these kinds of treatments in places like Britain. And that's certainly a valid critique. I'm sure my mom and daughter would still be waiting for their treatments, while my father and wife would probably be dead.

The key point, though, is that these treatments didn't just come out out of the blue. They were developed by drug companies and device makers who thought they had a good market for things that would make people feel better.
