The Labour Party, of which she is so enamoured, have done more to widen the gulf between rich and poor in the UK than the Conservatives she so reviles.
Mind you, why she thinks that the privately-educated, unfeasibly rich Gordon Brown would have any more of clue about how "poor people" (as she patronisingly puts it) actually live than the privately educated, unfeasibly rich David Cameron is anyone's guess. Not that Cameron has any intention of replacing the welfare state with charity handouts, but hey ho.
Stick to writing shit-but-popular books, Rowling.
