Atlantic County has failed to hire a director for a planned million-dollar development corporation, a setback for a wider plan to steer the sluggish regional economy away from an unhealthy dependence on low-wage casino industry jobs. Even after a substantial search this spring and summer, no candidates from outside South Jersey could be drawn in to run the development corp. Instead, Max Slusher, the Atlantic County Improvement Authority’s (ACIA) economic development head, will perform double duty in the role for an interim period, the county’s chief of staff Howard Kyle said in an interview Monday. Although the non-profit development corporation, which should have about $1.2 million when it is fully funded, found candidates for the executive director gig, one turned it down for a better-paid alternative, and another withdrew, apparently because they couldn’t quite be persuaded to move to Atlantic County, Kyle said. Low local salaries and difficulties attracting workers to the county were both issues that were highlighted in a report by Austin, Texas-based consultants Angelou Economics that was commissioned by the ACIA and published a year ago.
