What happened to prices between 1966 and 1975

Between 1966 and 1975, the Consumer Price Index went from 32.4 to 53.8. Cumulatively, prices increased 66.0%, which works out to an average of 5.80% per year. Put differently, a dollar in 1966 bought what $0.60 buys in 1975.

Consumer prices rose 2.9% in 1966, nearly double 1965’s 1.6% as Vietnam War spending kept climbing without an offsetting tax increase, pushing the economy closer to capacity and prices higher along with it. Medicare coverage took effect that July 1, extending federal health insurance to roughly 19 million Americans age 65 and older under the program signed into law the year before. The Federal Reserve had already moved to cool the overheating economy, raising its discount rate the previous December over White House objections; the tightening carried into 1966 as the first postwar credit crunch, freezing parts of the housing and municipal bond markets even as inflation kept climbing. Congress widened the wage floor’s reach that September 23, when the Fair Labor Standards Amendments of 1966 set a $1.40 minimum wage effective the following February and extended coverage to roughly 9 million more workers in retail, hospitals, schools, and other services not previously covered. Consumer prices finished 1966 227.3% above their 1913 level. First-class postage held at 5 cents, and the minimum wage stayed at $1.25 an hour for the rest of the year.

The destination year: 1975

Consumer prices rose 9.1% in 1975, easing slightly from 1974’s 11.0% but still running far above anything the country had experienced before the decade began. The recession that started in November 1973, the deepest since the Great Depression, bottomed out that March, yet unemployment kept climbing through the year and touched 9%, a combination of high inflation and high joblessness that had no precedent in the postwar data. Vietnam ended that April 30, when North Vietnamese forces captured Saigon and the last Americans were evacuated by helicopter from the U.S. embassy roof. Fiscal strain hit closer to home too: New York City, facing bankruptcy after years of borrowing to paper over budget gaps, asked Washington for help that October. President Ford’s initial refusal produced the Daily News headline “Ford to City: Drop Dead,” though he ultimately signed a federal loan package that December. Amid the gloom, Bill Gates and Paul Allen founded Microsoft that April in Albuquerque, New Mexico, to sell a version of the BASIC programming language for the Altair 8800, one of the first personal computers sold to hobbyists. A median household earned $11,800 in 1975, a new home sold for a median $39,300, and first-class postage held at 10 cents, unchanged since 1974’s increase. Consumer prices stood 443.4% above their 1913 level, with the decade barely past its midpoint.
