Low interest rate is an addiction. Take a look a the Fed fund rate, after every financial crisis/recession, the Fed increased interest rates but it never recovered to the previous levels. It seems businesses and even governments prefer interest rate to stay low for the long run. It is easy to understand why businesses prefers low interest rates. As governments around the world are more and more in debt, raising interest rate would increase governments' interest cost. I guess, no government would like to pay more. Any comment(s) is (are) much appreciated.
