A lot of the cities build subway or tram stations in underdeveloped areas as a precursor of future expansion. And it works - after subway stop starts to work more developers start to build high-rises, shops, people start to move there from other underdeveloped areas without prospects of having a subway station. I see this article as an excuse against proper city and public transportation planning. It works everywhere but US, so maybe it's time to stop arguing and follow the example of other countries?
