I ignore the janitor because of the obvious wealth disparity between us. He works just as hard as me but is doing a job nobody likes and is paid less for it. It's completely unfair. And when I just see the janitor it's all I think about. This article is like, be nice to the people you step on. Yeah. I don't disagree with that sentiment.
I see what you're saying and I'm half way there with you. The important things are: a) don't ignore (just in the same way you won't ignore any other person, it's not a status thing, just a human thing) b) don't patronize - the comments in this thread and the general "be nice to poor people" has a feel good condescension written all over it, which you're rightly calling out. But it is possible (and baseline important)…
Feel good condescension is exactly my point. It's the perfect phrase to illustrate what I'm trying to say. Thanks.
