Well it does tell you what the sources are, which I think was more the point than providing an accurate number despite reporting it to two decimal places. Data availability is obviously a factor here (otherwise median income differences are arguably a lot more representative than mean income or GDP per capita differences) On a similar note, I'd argue that "unequal society" was a better label than "class divide", which usually implies lack of social mobility and fractured social groupings rather than simple ranges of income. But it does tell you exactly how they calculated what it calls the "class divide"
