"The avowed intent of the Labour party (or at least until Tony B. Liar) was to advantage the less advantaged. That of the conservative party was to retain advantage for the already advantaged."

True(ish). But I believe that Labour lost the last election because people were fed up with Blairism (control freakery, empty rhetoric and hypocrisy on stilts!) and the Tories failed to get a majority because a significant (but still not large enough) proportion of the electorate had woken up to their true nature.
