Regardless, poor and rich are relative terms; it's a continuum. You can never be "poor" and you can never be "rich." You can only be poorER, or richER, than somebody else. But there will still always be someone else poorER or richER than you. Ask Steve McQueen if he's rich, and he'll say well I'm not as rich as Paul Newman. Both dead now of course, but they once squabbled over who would get top billing in The Towering Inferno.
I think what I'm saying is that in some way, "poor" is in your mind, and as soon as you consider yourself poor, you are poor. I still wouldn't fault the author's friends for saying they're "too poor" to afford something; it is literally true. They're "rich" enough to afford food, sure, and I guess that offends the writer's sense of victimhood. The whole drama of this piece takes place in the writer's mind. It's a story of falling tragically from a place of privilege. People are "poor" every day and don't feel the need to write an article about it and nobody asks them to.
