Some dozens of years ago, there was a debate conducted between people insisting that "this loaf of bread must be redistributed," and the others who said "instead of worrying about redistributing it, cutting differently, let's make it bigger." A third possibility was not imagined: that the loaf may be shrinking. But it is now a genuine possibility. It is even acting upon already, like in the case of the American invasion of Afghanistan and of Iraq in order to secure the supply of petrol for the Americans addicted to gas-guzzling cars.
