Governments are deemed to succeed or fail by how well they make money go round, regardless of whether it serves any useful purpose. They regard it as a sacred duty to encourage the country’s most revolting spectacle: the annual feeding frenzy in which shoppers queue all night, then stampede into the shops, elbow, trample and sometimes fight to be the first to carry off some designer junk which will go into landfill before the sales next year. The madder the orgy, the greater the triumph of economic management.
