I want to know the answer to the following question:
What did Raghuram Rajan speak of?
All the background I'm provided with is that "Not surprisingly, the Austrian economic school regarded the crisis as a vindication and classic example of a predictable credit-fueled bubble that could not forestall the disregarded but inevitable effect of an artificial, manufactured laxity in monetary supply, a perspective that even former Fed Chair Alan Greenspan in Congressional testimony confessed himself forced to return to.". Is that enough to answer the question?
Answer: no
