To be clear, when interest rates cannot be used to control inflation, as is the case in almost every developed country now (and many others as well) because official interest rates are at, or near zero, tax is the only tool available for this task.
Interest rates are at near zero as a method of controlling inflation twatto. You know, to stop inflation being too low? And if we find that inflation rises then we can, of course, raise interest rates to control it the other way around, to reduce it.
Seriously, why does he think interest rates are at zero if it’s not to control inflation?
