This is an interesting blog post that uses a graph to show that over the long run, economic growth swamps short term fluctuations in the economy. The graph also tells the story mentioned in class that only the massive spending prompted by the world war pulled us out of the Great Depression. The overriding message of the post seems to be that historical trends indicate that we will pull ourselves out of this current mess; the fear that has captured the public is probably natural but that in the end long term growth will prevail.
Another great site for visualizing data is FlowingData. This example shows some interesting ways to visualize consumer spending.
Another good piece is this one in Forbes which provides a fair overview of the history of economic stimulus packages.
