1980 sat at the very peak of the Great Inflation. Prices rose 13.5% in that single year, mortgage rates were climbing toward 16%, and the Federal Reserve under Paul Volcker was administering the painful interest-rate medicine that would finally break the inflationary spiral, at the cost of the deep 1981–82 recession. No single year looms larger in how Americans think about inflation.
