As for "useful employment," a large open air prison like Gaza with strangled imports and exports doesn't offer too many opportunities other than smuggling or working for UNRWA. The fact that so many Palestinians are willing to risk their lives by working in tunnels or trying to cross into Israel shows how eager they are to find employment.
