Well, of course. I would argue, however, that most spend far more on food than they need to, and likewise for shelter - maybe not so much poor Americans, but in my experience middle class, upper-middle class and above Americans spend absolutely ridiculous amounts of money on their houses (together with lots of fallacies like thinking that renting is "throwing away money" and such). Healthcare is unavoidable, that's going to be a major expense for basically anyone.

At least looking around at other adults, I've noticed many spend really, really appalling amounts of money on things that don't really improve their lives in any way - and furthermore, that they seem to do so solely because it's what their parents did, or what they think is appropriate in society. Moreover, most consider it essentially an ironclad mandate that they work a 40 hour week until they're too old to work any longer.
