Economic Cause and Effect
Visit the New York Times page below for a cool flash driven Interactive chart that lets you compare various economic indicators like the Federal Budget surplus/deficit, changes in real income, home prices, number of jobs, personal savings, minimum wages, and most interesting to me, the Share of Income of Bottom of 99% (as percent of total income) going back to 1950. The chart makes it very easy to see who was in the White House and which party controlled the legislative branch in any given year.
