"cities are unique to shape economies" Jane Jacobs

As Martin Wolf in the Financial Times tells us:

"Over the past week the world has learnt of the death of two luminaries: Harvard's J.K. Galbraith, born in Canada, and Jane Jacobs, who ended her life there.
Canada did rather well out of the exchange. Galbraith was, indeed, a brilliant writer and polemicist, but Jacobs was a self-educated intellectual of astonishing originality." "Forget countries and, still more, the country-side. Look at cities, instead. These are, as they have always been, the engines of human advance."
