Fans of tough investigative journalism should probably avoid Channel 4’s How’d You Get So Rich? Presenter Katherine Ryan’s main tactic is to ask wealthy people how much they paid for something and, when they tell her, to repeat their answer in a tone of wondering admiration. Yet, despite her best efforts to keep it shallow, the programme does end up shedding some light on our peculiar attitudes to the very rich — and in particular our capacity to feel superior and inferior to them at the same time.
