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.

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.
