It always makes me chuckle when I go up to London - there, the wealth means people are throwing away stuff that would be eagerly bought second-hand in poorer parts of the UK. The net effect is that the waste disposal medium becomes more valuable than the contents, so a skip in London attracts loads of other people's rejects whereas a skip in Cardigan gets emptied as fast as it's filled (literally often true!) This was beautifully observed in an episode of One Foot in the Grave - Victor is forced to splutter "I don't believe it!" when he finds that someone has put a complete car in his skip overnight...
