A pet subject of mine

It is difficult to compare inflation really, it depends what currency and what items.
I think the world's financial "industry" has done much worse than it quotes in its published inflation calculators - probably by judicious choice of items to compare.
TVs are much cheaper than when I first started work, for example, but now we have home computers and game consoles with no real equivalent back then.
I finished my engineering degree and 2 years in service training in 1972 and got my first proper job as a Noise and Vibration research engineer. My first salary was £1100 per year. On that we married, saved for our first car and first house. Admittendly my generation nimby-ed our way into not building anywhere enough houses so here the price of houses has gone up from around 3x annual income to over 10x in places. I apologise on behalf of my generation for our selfishness and greed in this respect.
When I retired at the end of 2009 the starting salary for a job like that one was around £22,000 per year - 20x more than we had, and I am pretty sure I couldn't have lived as well on that in 2010 as I did on £1100 in 1972.
So based on living standards I would say the pound sterling lost at least 95% of its value during my working lifetime - whatever bank calculators say.
And it has maybe lost a substantial percentage more since 2010, some food items have doubled in price in that time.
My pension savings lost almost half their value following the 2008 collapse for example. Investments look like they do well, but compared to how badly currency has plummeted in its ability to buy stuff, nowhere near well enough.
The first pound I saved could have bought a 3 course lobster meal, or 5 imperial gallons (23 litres) of petrol when I saved it. Now it can buy half a loaf of bread or 0.71 litres of petrol.
Saving turned out to be mainly feeding the greed of the financial "industry".
