I think perhaps some people view poverty as a short term thing which can be escaped, without actually thinking that this kind of life is lived by people daily who simply do not have the wherewiothal to change.
It's not slumming it. It's not being on your uppers. It is life. Primark, cheap crap food, Macdonalds as a treat, school uniform purchase a fucking nightmare, this is every day reality and they have not know any different.
