Focus Healthcare on the Expensive Patients

Is it selfish that I really like this way of tackling rising healthcare costs because I am one of those expensive patients?

Here's my only concern, though. Obese people cost the system billions of dollars, but since 1/3 of Americans are obese, doesn't that dilute the effectiveness of focusing on the expensive few?

Clearly, in addition to treating the illnesses, we also need to treat the disease of what's causing obesity in America. I know it's a lot of factors, but you can't find the answer to all of them in the doctor's office.
