Much of the progress in medicine during the past half-century has involved expensive, high-tech diagnostic tests and therapies. The trend in this direction worries health economists and politicians because it has the potential to send already high health care costs into the stratosphere. Health care spending in 2017 reached $3.5 trillion, or a whopping 17.9% of the nation's gross domestic product, according togovernment statistics.

However, there is an important role as well for ingenious, low-tech, less-expensive approaches to improved health and increased longevity. The question is, how do we make them financially attractive?

The high-tech miracles will continue to garner headlines, but to control health care costs we will also need simpler and relatively inexpensive innovations. That has policy implications. Marine Corps Commandant Gen. David Berger wrote (in a different context): "We must continue to seek the affordable and plentiful at the expense of the exquisite and few." That applies to health care as well.
