Are Americans Getting Richer? (Washington Post Editorial Board, Feb 20, 2026)
The premise of the index is simple: how many hours do you need to work, compared to the month or year before, to be able to afford the “basket of goods,” which is a standard set of household items and services that comprise the Consumer Price Index used to calculate inflation.
The “time price” is how many hours of work it takes to purchase the basket of goods. The “abundance” is how much of the basket one hour of work can buy. The story told by the index is a very good one: since recordkeeping began, “abundance” for average private sector workers comes out to a net increase of 13.8 percent.
