Interesting, I have two conflicting feelings about this. On one hand I agree with you and I am super paranoid about being poor. On the other hand, one thing that I definitely learned from growing up poor (I like the original article say "it’s very small (think ~900 sqft)", cause I had stable housing when I was growing up and it was 600sqft for 3-4 people ;)) is how little you need to be happy.

In college, when we were somewhat better off but before I could work a real job, I often had a choice of either paying my internet bill, buying (cheap) cafeteria lunches, or buying beer. So, unless I wanted to and could find a part-time job, I liked to joke that my choices were - hungry, sober, and online; sated, sober and offline; and hungry, drunk and offline. I was still happy. After I got my first job, sometimes I would get impostor syndrome and become afraid of losing it; then I'd be like, well I used to be happy when I was choosing between the three options, so anything on top of that is just a nice bonus. As long as I have 150sqft of housing, some food and an internet connection I will be fine. I like to think about that every time I'm afraid of losing my current level of privilege.
