Unless one has experienced the absolute deprivation of deep poverty, "you just don't know this," said Deisha Bradley, 30, a North Philadelphia mother of a 3-year-old girl who was recently laid off from a job as a security guard and now has no income. She may not get state unemployment insurance because she worked part-time. She receives $358 a month in food stamps, the equivalent of around $4,200 annually, nearly one-fourth the poverty rate for a family of two.
