When you see the poet laureate saying that every child should have readUlyssesand that you're just giving up on children if you think it's elitist - does that include children with special needs or whose first language isn't English?

It is a mistake to use highfalutin language when you advertise to uneducated people. I once used the wordobsoletein a headline, only to discover that 43 per cent of the housewives had no idea what it meant. In another headline, I used the wordineffable,only to discover that I didn't know what it meant myself.
