It is useful. Robert Owen said man cannot be a proper subject for praise and blame. If he was right then of course that has implications. Isn't it suspicious if you used to use a desert argument ("we pay this guy because he chose to work hard and so deserves it"), then you move to a utility argument ("we pay this guy because paying people like him more leads to good for all of us"), and miraculously the right payment works out to exactly the same?
