Quantifying the worth of someone like this is notoriously difficult.
One of the issues the BBC has is keeping its presenters from being lured away by higher salaries in the commercial sector.
Of course, many people would argue that lots on the list would be no loss, but the ability to appeal to a huge and diverse national audience, which is what the BBC's presenters must do, is a nebulous
concept at best.
Radio and TV has gone the way of football, ludicrous salaries disproportionate to either talent or output, but everyone is on the merrygoround, with no sign of it slowing down.
