Don't forget the University of Rochester. It has become the largest employer in Rochester. About to open a new $68 million cancer research center and will soon have one of, if not the most powerful lasers in the world. Also focusing on fusion research. Amazing stuff happening over there.
I agree that Rochester's job market is going downhill in comparison to much of the nation, but it is certianly in the best position in all of upstate NY and may just make it through.
