The shrinking health spending gap
One of the laws of health care baked into the heads of every policy analyst is that health care spending almost always rises much faster than GDP. Except it hasn’t really been doing that since 2010, and the gap between health spending and GDP growth is projected to continue to be small through 2026.
What we don't know: The cause. We don’t know why the gap has closed (experts disagree and emphasize different factors), and we don’t know if the narrowing is permanent or if the gap will widen again.
