Just in time for the next presidential election, health care spending is starting to take off again. Through 2024, health care spending is projected to grow by 5.8% annually, on average, according to CMS. While this isn’t unexpected—health economists across the political spectrum expected health care costs to start growing again (and growth rates are expected to still be lower than the long-run average)—the window for addressing health care costs in a less painful way is closing. Without better cost controls in the private sector, and without immediate reforms to Medicare, the health care sector is set to gobble up a full fifth of the U.S. economy in just 10 years.
