Quantitative Easing, Near-Zero Interest Rates, and Asset Price Inflation
The 2010s saw official inflation remain historically low — averaging just 1.8% annually in the US — but purchasing power erosion was far from absent. Asset prices (homes, stocks) soared while wages for most workers stagnated. A dollar's official CPI purchasing power barely changed, but the cost of a home relative to income hit record highs. Healthcare costs rose 30% faster than general inflation. College tuition tripled in real terms over two decades. The 2010s demonstrated that CPI can understate the cost-of-living pressures felt by ordinary households.
Between 2010 and 2020, US median home prices rose 62% while median wages rose just 23% — meaning a home was 30% more expensive relative to income than at the start of the decade.
£100 as a serious sum
£100 in 2015 was serious money for most households. This is past the weekly-budget range. A sum like this could fund a major purchase — furniture, a sewing machine, or months of rent. For a skilled worker it might represent a fifth of a year's earnings. Money people saved for rather than spent casually.

Pre-industrial calculations carry a wider margin of uncertainty.
Why does purchasing power matter more than just inflation percentage?+
A simple inflation percentage tells you how prices changed, but purchasing power shows you what money could actually buy in human terms. £100 in 2015 bought a specific number of loaves of bread, weeks of rent, or months of wages — context that makes the number real and tangible, not just an abstract percentage.
