There are two things I'd like to know more about for this:
1. Is the homeless person doing their survival in an area with a markedly lower median wage than the median wage their income is being measured against? (i.e. is "1/10 the median wage" an illusion created by including foreign communities in the 'median wage'?)
2. Is the homeless person's low income measured by excluding their income from in-kind handouts ("someone kind bought me a sandwich") and foraging ("I found a pizza in the dumpster")?
