Until relatively recently, mass political movements were still about basic rights of food, shelter, education and self sufficiency. The reasons fewer people vote these days, or turn up for political meetings, is that for the vast majority of us those rights have been fulfilled. These days it's in the adverts for mobile phones or foreign holidays where phrases like "Join the Revolution!" and "Cry Freedom!" are bandied about for a generation which knows nothing of their provenance. Just as now we have luxury illnesses to replace real ones, so now we have luxury politics.
