While higher inflation might help a rich, highly indebted, industrialist because his debt comes down relative to sales revenues, it hurts the poor daily wage worker, whose wage is not indexed to inflation. 3 Second, higher inflation is more variable. This raises the chance of breaching any given range around the target if it is set at a higher level.

Third, inflation could feed on itself at higher levels – the higher the target, the more chances of entering regions where inflation spirals upwards.
