I can recall two students I knew at Stuyvesant who lived in a couple of the more violent public housing projects who went on to college. My anecdote proves your anecdote wrong. That said I will need for you to come with studies and real data that show you are not wrong. This is because what you are saying has very real world implications that will hurt children who do need sometime up to 18 years of housing assistance so that they can also go on to college and become productive members of society.
