I don't the know the number of hours in 1951 that make up a year's worth of work (today we use 2000 as the usual number of hours), but 1951 US Census data seems to approximately bear out what I wrote: https://www.census.gov/library/publications/1952/demo/p60-010.html https://www.census.gov/library/publications/1952/demo/p60-01... : "The average person's income was up by 10 percent between 1950 and 1951, according to estimates released today by Roy V. Peel, Director, Bureau of the Census, Department of Commerce. For all persons 14 years old and over receiving any money income, the average (median) income was estimated at $2,200 in 1951 as compared with $2,000 in 1950. The median income of men, which has been rising steadily since the end of World War II, showed a record postwar gain in 1951. The 1951 median of $3,000 was about $400 above the 1950 estimate, and the proportion of men receiving incomes or $5,000 or more rose to 14 percent from 11 percent during the year."
