This chart, produced by the Bipartisan Policy Center based on CBO data from 2011, shows the projected spending on health care, social security, discretionary, and mandatory by the federal government, as a percentage of GDP. As you can see, for all our hyperventilation about social security, it’s relatively stable once we get about 20 years out. Discretionary and other mandatory spending are similarly flat over time. But healthcare… that’s what’s going to get us.
