Cities want to attract and retain young educated talent to fuel their knowledge economies, drive a tax base and create a community that can continue to grow by welcoming more new people in the future. Modern markets are insatiable and indefinitely incomplete.
That’s the clearest, simplest mission I can glean from all the chirping about celebrating gains Philadelphia has made in its old brain drain problem.
But last week at a Knight Foundation session with the Economy League of Greater Philadelphia, I wanted to push that thinking forward in two ways that I don’t think I hear often enough in that conversation: (a) the idea that too much change can in effect take away what is distinctive about a city and (b) that any real success would improve the lives of existing Philadelphians too, not just push them out like in other cities.
