All the Western central bankers have been drinking from the same cup for years. Poloz is no worse than  than the guy who preceded him, indeed Carney layed the groundwork for todays problems. They all took the same theory and know only one approach to take. They are all no doubt well educated, intelligent? All the Western countries are carrying too much debt and spend too high a proportion of their GDP on government. We are in for a long period of slow growth but throwing money at the problem and cutting interest rates will only make the final outcome worse.
