The official numbers are highly manipulated garbage, with many staple consumer goods and energy types excluded. If calculated the same way they were in the 70s, your 33% is well over 50%. In the music industry, some things are up over 100% since 2020.
That highly manipulated garbage is still pretty standardized way in the EU and US to calculate inflation. It is average and as we buy different things, on personal level it can be something different, but I think if you really would calculate it for you based on what you consume, it would not be far off. At the same time salaries have gone up. More so in the US compared to EU and especially here where i live. Likely one of the reasons why inflation here is already under 2%.
I think it was pretty nasty when covid hit prices went up because of ’anticipated supply chain issues’, companies made astronomical profits and contributed greatly to inflation.
If you use gibson prices only to calculate inflation, it is close to 100% in 5 yrs. But that’s corporate greed, not inflation
