The only thing I can come up with is that she’s the sort of self-made person who, thanks to the luck of her personal success, somehow forgot that poverty and economic injustice are still things and would rather see everyone who is still where she was in the Nineties-a struggling single mother trying to keep her kids fed by any means necessary-left to starve just so that SHE doesn’t have to finally start paying the share of tax a wealthy person SHOULD have to pay. Seems to be straight up drawbridging and nothing else with her. She even helped abet the antisemitism slur against Corbyn and his supporters.
