I've been there, done that. Rat infested apartments the whole deal. You want a quick and easy way to know if someone does not understand poverty? The phrase "buy in bulk" comes out of their mouth.
I got out of poverty by sheer luck; I got a job that included room and board and isolated me from shopping, which enforced saving discipline. I am interested in seeing if anyone else has been through this and has anything to add to the article.
