The California Health Care Foundation passes along this very cool graphic that shows how much who pays for health care has changed over the past five decades. Here's where we started in 1960.

And what health-care spending looks like now, in 2012.

The most striking change is how much out-of-pocket spending, represented by the orange lines, has shrunk as a percent of our overall health spending. Most of that has to do with the introduction of Medicare and Medicaid in 1965, which began picking up bills for seniors and low-income Americans. The federal government now spends half its revenue on health care, according to CHCF. For personal income though, that figure stands at a meager 6 percent.
