I couldn't find any publications when searching for "bls ordinary expenses" and google's AI says you probably meant "Consumer Expenditure Surveys". However after looking at some of the data, I'm not sure it's as rosy as you make it out to be. For instance if you look at consumer expenditures by income[1], you see that the average across all consumer units is $87.9k of post-tax income against $77.3k of "average annual expenditures". That sounds okay until you look at some of the lower income groups. The $50k-69k group has $56.5k of post-tax income against $59.5k of expenses, which implies they're getting into debt to finance their lifestyle. That's true for every income group under $69k.
