Who will challenge this creeping monoculture? Not the main political parties. They offer only minute variations of the same pro-consumption product; for Labour, the Tories and the Lib Dems read Tesco, Sainsbury and Asda. They even behave like retailers, testing policies to see what works best and adjusting them accordingly as they compete for market share. Meanwhile, retailers appropriate what’s left of the language and culture of democracy. Walkers crisps holds the biggest election of the year for its new flavours; Costa Coffee claims “the people have voted” and that seven out of 10 prefer its brand over Starbucks.
