Honestly you're right that inflation can benefit the well off, but I don't buy the conspiracy theory angle. "The Establishment" has been holding inflation rates at historically unprecedented lows for the last generation. It's been the number 1 priority for central banks since the early 90s. The last time the UK inflation rate was above 4% was over 20 years ago.
