People must take a modicum of public responsibility for each other even if they have no ties to each other.
Jane JacobsCities need old buildings so badly it is probably impossible for vigorous streets and districts to grow without them.... for really new ideas of any kind--no matter how ultimately profitable or otherwise successful some of them might prove to be--there is no leeway for such chancy trial, error and experimentation in the high-overhead economy of new construction. Old ideas can sometimes use new buildings. New ideas must use old buildings.
Jane JacobsTo seek "causes" of poverty in this way is to enter an intellectual dead end because poverty has no causes. Only prosperity has causes.
