Always enjoy your videos! I would like to see a video on the commodity markets, and how the current economic crisis has affected them.

I enjoy Mr. Hirsch's video clips but found this one slightly over simplified. Mr. Hirsch only described interest rates in regards to personal savings. What about interest rates in regards to the availability of money. When the federal funds rate is low, it is easy for banks to lend to each other. This then results in a free flow of money. With a free flow of money people are able to get loans and spend more freely. When the fed funds rate is raised, money is "harder" to get, resulting in less flow of money and therefore less spending.
