This is a long read but worth it. I don't like to only complain but praise too, so good on the writer Christopher Leonard. The part about low interest rates causing a farm land bubble in Kansas was enlightening. I lived through the extreme interest rates of the late 70's and subsequent crash caused by the policies of Paul Volcker and it wasn't pretty, but then I was able to buy a house in the mid 80's at a decent interest rate.
Edit: Volcker
