the neighborhoods are falling apart because we are underpaid, undereducated, and so many of us have been living like this with the second or third generation. we don't even know how to change. despair is a way of living. ian: this is where it resides on a bleak row of row houses, the end of the line for americans gripped i poverty. the last family living on the block. three generations of the stewart family crammed in. they are months behind on the rent, unpaid bills are piling up, unsurprising when they have $30 a day to survive. >> i love you, be careful. have a good day. evictedy have been before, forced to live in an abandoned home. they have toecause stay wrapped up in blankets. they don't want to get out of bed. they get bullied in school because of it. it hurts. they got to where they did not even want to show their faces outside, but we had no choice but to live there because of the economy. >> i've struggled for seven hard years. ian: what pressure does that put on your relationship? >> we argue and fight all the time. i love this woman, she is my her goiend, but to see through

we are underpaid, undereducated in so many of us have been living like this for the second and thirdation until we don't know how to change. despair is a way of living. and this is where it resides, on a bleak row of abandoned homes. this is the end of the line for americans gripped by poverty. here, we met the last family living on the block. three generations of the stewart family are crammed in here. they are months behind on the rent. unpaid bills are piling up, not surprisingly they just have $30 a day to survive. i love you. be careful. have a good day. they've been evicted before, forced to live in one of baltimore's many abandoned homes. it hurts, it hurts that they have to stay wrapped up in blankets all day because they are cold. they don't want to get out of bed because there's no heat to keep them warm. people talk about us. they get bullied in school because of it. it hurts. they've got to where they don't even want to show their faces outside. but we had no choice but to live there, because of the economy. i've been struggling for seven years. seven hard years. what pre
