There was actually a very interesting discussion on econtalk that easily came to the conclusion that interest rates aren't artificially low. The primary, possible reasons they saw were that new industries in the West need fewer initial investments than traditional industries (compare the cost of starting a new refrigerator factory to starting a tech startup) and that Asian countries with much higher saving rates are making up a larger portion of the economy. One point they made is that interest rates were already very low before the recession and QE.
