I'd also like to bring up that the poverty line is, by and large, rather arbitrary. My family lives comfortably in a middle class lifestyle with almost zero debt (barring mortage) and enough disposable income to use on more than just basic needs. This is less than $25,000 a year, single parent, three member household. In other words, just barely above the official poverty line. Yet, you could make absolutely zero argument aside from that line that my family is poor. With a nice house (and a $1000/month mortgage), and more than just the basic necessities like a cell phone plan for all three of us, high speed internet and cable, two vehicles, and sending me through college.
tl;dr poverty line is probably better considered an 'at-risk indicator' than it is an absolute indicator of poverty.
