Super Rich is trying to illustrate how strange life is in such an unequal society. Because this state of social inequality is the only reality many of us have known, we can’t imagine how things might have been different. George Irvin argues that as recently as the 1970s the United States and Britain used to be far better at helping the less well off, in a way that we don’t any more. For example, there was a point during the Second World War when Roosevelt wanted people to have 100 per cent income tax when they were earning over the equivalent of £200,000. He thought that nobody needed more than that.
