The idea of Section 8 housing was to move poor people to middle class neighborhoods to do what? Stossel says "to learn good habits." So this means that poor people have "bad habbts" that keep them poor. In other words, there is a reason that they are poor, it is not just the luck of the draw. Of course, if you move poor people with bad habits into a middle class neighborhood, and those habits continue and result in an increase in crime or a lack of commitment to the upkeep of the home, then home values decrease. This decreases local real estate taxes, reducing funding to schools, requiring the state and/or feds to spend more on education. Obviously no one thinks past their nose in DC.
