A non-existent free lunch

[Current presidential candidates] don’t merely argue that preventive care delivers good bang for the buck. They argue that it delivers good bang for no bucks whatsoever. And this is where the candidates are overreaching.

No one really knows whether preventive medicine will save money in the long run, let alone free up the billions of dollars a year needed to help pay for universal health insurance. In fact, studies have shown that preventive care — be it cancer screening, smoking cessation or plain old checkups — usually ends up costing money. It makes people healthier, but it’s not free...

For a new program to work, it has to reach people who are not being helped by whatever exists now — and who thus will be among the most difficult and expensive patients to treat. The program would also have to treat a whole lot of people who never would have gotten sick.
--David Leonhardt, NYT, on why preventive care is a good but not a free lunch
