Not to mention I see no mention of healthcare costs. I - a single 30-something with some chronic issues, easily spend $5k on healthcare a year - more if I get hospitalized, which has happened 3 times in the decade.

That’s not even counting the portion that comes out of my check.

What kind of answer are you looking for? There are people who live on less than $40k without even meaning to. It's not an outrageous number, but sure, would be harder with chronic health issues and so-so insurance.
