The alternative to this is that, as Toynbee suggests, we must all be re-educated in order to hate inequality. Then we would ask for, and would get, greater action to reduce it. Democracy would indeed produce what we want but only after we’ve elected another electorate to accord with a Guardian columnist’s ideal society. That seems rather against the spirit of democracy, even it was Brecht’s solution to the same problem.
Attitudes toward inequality do differ across societies, it’s no great surprise that their levels of inequality differ as well.
