What happened to prices between 1928 and 1975

Between 1928 and 1975, the Consumer Price Index went from 17.1 to 53.8. Cumulatively, prices increased 214.6%, which works out to an average of 2.47% per year. Put differently, a dollar in 1928 bought what $0.32 buys in 1975.

Consumer prices fell 1.7% in 1928, the second straight year of mild decline even as the stock market climbed sharply, a widening gap between asset prices and the cost of living that later economists pointed to as an early warning sign. The Federal Reserve tightened policy repeatedly over the year, raising its discount rate in an effort to slow the flood of borrowed money pouring into stock purchases without derailing the broader economy, a balancing act it ultimately failed to manage. Herbert Hoover won the presidential election that November, defeating Democrat Al Smith on a platform built around continuing the prosperity of the Coolidge years; few voters or policymakers anticipated how quickly that prosperity would end. First-class postage remained at 2 cents, a price that had now held for nine straight years.

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.
