Camden, New Jersey is a struggling city, plagued by poverty and violence and haunted by comparisons to thriving Phialdelphia, just across the Delaware River. Back in 1996, the state subsidized the construction of a major performing arts center inside Camden’s massive Clear Channel-owned Tweeter Center. But while the for-profit arm of the Tweeter has thrived, the non-profit arts center has been a dismal failure, and some are questioning the massive taxpayer subsidies that continue to be pumped into the project.
