What did the Druids know about economics?

Well, they were definitely fans of George Bush and Tony Blair's 'shop to save the economy' plan. I just read that the ceremonial dumping of precious objects in rivers and pools (as they did in Llyn Cerrig Bach) may have been a religious cover for stimulating spending: dump your old stuff and buy new! Keep the economy liquid!

Which is fine when the entire population of Europe is a few million at most, not so great when 60 million not so ancient Britons go to Primark every week…
