The resulting economic growth is something that must be discussed when analyzing and critiquing the streetcar system. If you spend $100 million on a transit project and it results in $500 million in economic investment then you are getting a pretty good return. The neighborhoods get upgrades in infrastructure and the city increases its tax base. Mr. Arum completely fails to take this into consideration. I’m not so sure fixing potholes and adding left turn lanes would result in the same return on investment.
