Minimal Quality of Life
https://lisep.org/mql
Funny that running shoes gets a full category. Of course, if they are talking about serious runners, then the supershoe revolution has made running shoes vastly more expensive (generally in the range of $225-$300). I've never tried a pair, but if you care about your times or you train high volume and have any joint issues, you are probably buying them.
I also wonder how much travel and eating out are weighted. I don't think the "minimal quality of life" needs to have a lot of those, though travel to see aging parents is a substantial part of our budget these days.
Also, the first quartile, the poorest, did fairly well from 2010 onwards except for the first Covid year... though the recent budget bill might change that, since medical costs are the ones furthest to the right in the graph and about to get more expensive for a significant number of people in that bottom quartile.
