Should teachers be more like Florence Nightingale?

At a seminar organized by IFN a new book about the teaching profession by Johan Wennström was presented. "It is high time to start talking about the teaching profession as a vocation again" said Wennström.  Isn't that a ticket to low pay for teachers? No, said Wennström, there is no contradiction between working for duty and a calling, and having a good pay.
