I was citing Adam Smith in a lecture by way of introducing the concept of specialisation (this Scottish moral philosopher now appears on £20 notes in England). I wanted to make the connection between specialist skills and knowledge and greater earning potential.
I then alluded to the gender debate that has been livening up PR blogs this week. Then why, I asked, in a female-dominated practice did a recent research study for the CIPR point to a continuing gender pay gap in favour of men in public relations?
Perhaps, suggested a student at the back, it’s because men tend to choose the better-paid specialisms such as financial PR and public affairs over general consumer PR work. Could be.
PR Studies 
In my limited opinion (as you know there are a limited number of boys on the course) it is not so much to do with the field of PR they want to go into at university- all the boys I know want to do sports pr and all the girls consumer/celebrity.
