I think this last paragraph in the article really reflects the epidemic that we are facing:

“While Roehrig finds little evidence that recent reforms changed the rate of growth, he said that over decades, the amount by which increases in health spending have exceeded GDP growth has narrowed. “There’s more evidence now that we’ve been on a long-term steady decline in the excess growth rate,” he said. The good news is that if the trend holds, U.S. health spending will eventually stabilize. The bad news, according to Roehrig’s analysis, is that it wouldn’t happen until health-care accounts for about 25 percent of the American economy.”
