Inflation was high for quite a number of years before volker, they kept raising rates but then backed off from the economic pain and never succeeded in killing it completely. Volker came in and raised rates to the point where inflation was done. The point being, they can try to kill it first time, or maybe they have to raise even higher later on which would be even worse for the problem you're talking about. Also, they're on record as being fully aware of this.
