Chart of the Day, Total Government Spending Edition

Just yesterday I found myself wishing for a chart showing combined spending for federal, state, and local governments as a share of GDP over time. Today, via Instapundit, I see that our friends at the Mercatus Center have hooked us up:

And wait! The news gets worse:

Today federal, state, and local expenditures as a share of GDP are back at the highs reached during World War II. This time, however, we are unlikely to see a swift decrease. Wartime expenditures on items like weaponry and salaries for conscripted soldiers were relatively easy to wind down. The bulk of current and future government spending is on entitlement programs like Social Security and Medicare. This variety of spending is nearly impossible to reduce in the near term.

Whole thing here.
