PPP-adjusted disposable income per capita (meaning, after all the necessary expenses) is by far the highest in the world: https://www.statista.com/statistics/725764/oecd-household-di...

Food spending as a portion of total expenditure is the lowest in the world: https://ourworldindata.org/grapher/food-expenditure-share-gd...

Out of pocket health care expenditure as a share of GDP per capita is fairly low in comparison with other wealthy nations. Of European nations, only Monaco, Luxembourg, the Netherlands, and France are lower (and not by much!).

Transportation spending is indeed higher in the US than most of the developed world, but it doesn't eat away much at the increased disposable income per capita -- proportionate to household income we're talking about a few thousand dollars higher, and most of that is a very recent development as costs went way up over the last few years.
