Susan's point is that we should be more focused on preventative medicine and not so much on reactionary medicine.
A large portion of our health care expenses are due to lack of preventative care.
Reward doctors for having healthy patients, not for prescribing medications and running tests.
Maybe so, but I like knowing that I can abuse my body and still make it past age 80. Bring on the stents, pills, surgery, cutting, genetic reengineering, chemicals, biotech yadda yadda I'm all for it. I'd much prefer that to a boring old holistic lifestyle nibbling on greens and being one with the earth whatever the hell that means.
Why would I want to live my way? Because I CAN, that's why. Furthermore, I've never had a doctor who didn't encourage healthy practices. It's a myth and urban legend that doctors don't want you to get well so they can make more money. Every orthopedic surgeon I've ever met discourages running as exercise. From my own experience that advice is spot on.
So I like knowing that if I need it, expensive knee replacement surgery will make me almost good as new. So while others are out drinking their herbal tea limping around, I'll be sitting on the couch watching TV with my brand new perfect knee! It doesn't get any better than that.

Of course the knee will probably be made in China by some factory worker who has an online TCM store on ebay geared towards impressionable Westerners. CHACHING!
This isn't an issue of cultural lifestyle anyway, it's an issue of personal responsibility. It's like that joke:
So the Zen master steps up to the hot dog cart and says: "Make me one with everything."
The hot dog vendor fixes a hot dog and hands it to the Zen master, who pays with a $20 bill. The hot dog vendor puts the bill in the cash drawer and closes the drawer.
"Where's my change?" asks the Zen master. And the hot dog vendor responds: "Change must come from within."
