As such, it surprises me that compensation and challenging work go above it. Even if I were being paid $200,000 a year to do cool work, if I had to deal with mega social and management issues, if I had to stay there I'd be deeply unhappy.
(Of course, the flip side is if the perfect environment offered a salary of, say, $10000 a year, that might be just as useless.. which makes polls like these a bit pointless really).
