Inflation of 4% sure isn't as good as 2%, but generally speaking the inflation rate in the UK appears to hover around 2-3% during "stable" periods. https://www.macrotrends.net/countries/GBR/united-kingdom/inf...

Compare pre and post 1945. The 1800s had a depression every banking cycle, now we just get recessions. Bank failures no longer take down your life savings. The king of England doesn't sometimes surreptitiously start putting copper in the gold coins to fund wars any more (e.g. inflation). GP's chart is pretty impressive, actually. Aside from the 70s oil shock, inflation is pretty constant, especially in the last couple decades.
I might believe this is M2 hadn't increased 4x since 2000 https://fred.stlouisfed.org/series/M2SL
However inflation!= growth in the money supply. A lot of the reasoning behind that growth was because inflation was persistently below the 2% target for the entire period up until 2021. That’s two decades of stubbornly low inflation, despite the feds best efforts in juicing the money supply.
It’s maddening how common it is for this forum to treat the issue as so simplistic and formulaic as though policymakers are somehow dunces compared to software engineers.
One of the reasons why the M2 supply increasing wouldn't directly correlate to inflation has to do with global demand to hold the asset in reserve.
So the argument I don't think is bad, just misguided in the sense that once the global demand for currency reserve is saturated the party is over for increase in supply with out a very direct affect on inflation.
However it usually is a more simplistic conversation that glosses over the challenges of actually making policy at the fed.
The post you replied to referenced the St. Louis Fed chart saying 4x M2 growth from 2000 to now. The page I referenced shows the same 4x M2 growth for the UK: from 750k at 2000 to 3000k at 2023 (values in GBP Millions). Virtually identical.

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.
