The final national health care spending numbers for 2022 came out earlier this month. Turns out we're pretty much exactly where we were in 2010 when the ACA passed: health care costs the nation just over 17% of GDP. Showing just nominal dollar amounts masks that incomes and GDP have grown just as much as health care spending since the ACA passed, meaning that relative health care costs have been more or less frozen for over a decade (the transient COVID spike aside). Astonishing and unprecedented stuff.
