5. In 2020, Oren Cass, executive director of American Compass, a right-of- center policy group, unveiled a measure that he called the Cost-of-Thriving Index. His basic conclusion is that in 1985, a single-income family could afford the basic trappings of middle-class life - food, housing, healthcare, transportation, their children's college - from working just 39.7 weeks at the median wage for men aged 25 and older (then $443 a week). In 2022 that median wage hit $1,219, but it would take 62 weeks of work to afford those same things. This measure of the cost of thriving yields a 36% decline in the standard of living since 1985.
