Towards the end, he said that he felt guilty about leaving projects soon because not everyone could leave. Writing in the Forward, Stephen J. Dubner said Vankatesh spent "the better part of a decade" in the projects. Looking back, I'm unhappy with this wording because he didn't actually live in the projects. He visited the projects. He wrote about apartments with many utilities not working, but he didn't actually experience that. I almost feel like his work would be more effective than it already is if he lived there for a while, even if only six months. If he himself were to barter for goods. If he had experienced it, he might have been able to better understand the barter system in the projects.
