I think this isn't a measure of inflation per se, because productivity changes are big over the decades. But I do think looking at costs in terms of hours of work is really helpful.
I think back to an event in some HS extracurricular when a group of students got to ask questions of a gubernatorial candidate, and one kid asked if he was going to do anything to make college more affordable at state schools, and this candidate (perhaps keenly aware that almost none of the students could vote) basically laughed it off and talked about working at restaurants to put himself through school (I think in the 70s). How many hours of (unskilled?) labor was a semester of tuition then, versus 30 years later? How many hours was a tankful of gas, or rent for half an apartment, or a heating bill? How feasible is it really to work one's way through even a public school?
