to be sure, a lot would be useful in disaster relief. Someone who could astral project to survey a scene from survivors, or in search-and-rescue. Ability to tunnel would let you get to victims particularly if you have the handy trait of making the stuff you tunnel through vanish. Ice control powers for fire-fighting. Telekinesis or magnetism during wartime would be wasted on the battlefield; they would act as a marvelous force multiplier to deliver supplies to beleaguered places.
But think of the non-high-dramatics fields.
Animal-control would make a great circus act. Plant control would produce fantastic gardens and landscape. Ice control for refrigeration or building an ice rink. Viewing times gone by -- historian, or accident investigation. A compelling voice that lasted a long time would work wonderfully for those who want to give up the drugs. Flying powers would work wonderfully for a reporter who wants to get shots from the air. Invulnerability for a stunt double.
The possibilities are enormous.
