I also think that whenever you want to use the word “poor” in public, you (or anyone!) would do well to clarify the following two things:
*By “poor,” here, it sounds to me like you’re actually talking about Larry Winget’s “broke” — people who are middle (or maybe working) class and are overspending, rather than people living in actual crushing poverty. Maybe it’s cheesy, but I feel like at least giving the nod to that fact is a good plan.
*Systematized oppression happens. Sure, some people don’t get opportunities through sheer bad luck, or through not doing things to increase their exposure. Some people don’t get them because they have the “wrong” gender, skin color, or sexual preference, because they speak with an accent or have disabilities. Or because they were brought up in a working-class family and so their behavior is not just like that of the middle-class people holding the jobs they aspire to. These are all things that people — consciously or not! — make decisions based on, and that means that for some people, the kind of lucky break that can make a big difference is much harder to come by. I feel like acknowledging the role these kinds of discrimination play is also probably a generally good idea.
